Entry ID 14393 3.3.14
All helmets used in road racing and flat track must have been manufactured within the prior 60 months 72 months of the date of competition and meet Snell (or equivalent) standard at the time of manufacture. (Patrick McGraw, Member #6278)
Rule Change Rationale The Snell Memorial Foundation’s recommends replacing helmets after “5 years of normal use...”NOT 5 years from date of manufacture.Everyone knows that new helmets sit in a warehouse for AT LEAST a year before they are sold. In most cases, it’s even longer. Sitting on a shelf does NOT constitute “normal use.” AHRMA would still be in compliance with the Snell recommendation with a 72 month from date of manufacture policy. The Snell recommendation is below, copied directly from the SMF website:
“Unused helmets stored in good condition do not automatically expire after five years. Replacing helmets every five years is a judgement call based on testing helmets used by the California Highway Patrol by Dr. George Snively. Wear and tear, the simple act of putting on and taking off helmets, damage the comfort pads and energy absorbing foam liner over time. Helmets with worn-out pads are at least one to two sizes larger than helmets in new condition. A poorly fitted helmet makes it more likely that the helmet will shift too much or even come off the head during a crash impact. For these reasons, Snell recommends replacing helmet after five years of normal use.“
Committee Recommendation: Reject (Unanimous)
Committee Discussion: Not aligned with industry standards.
Board Discussion: Motion to vote GT, Second EV
July Board: no (1 yes JH / 10 no)
Entry ID 14429 3.3.14
3.3.14 Helmets must be used in all AHRMA competitions and practices. Helmets worn in road racing and flat track must be full-face type and certified by the manufacturer by having a sticker affixed to the helmet stating the helmet meets or exceeds the Snell M2015 2020, Snell M2025, FIM BSI 6658 Type A (“Blue Label”) , FIM ECER22.05, ECE 22.05 (accepted through 2027), ECE 22.06 or FIM JIST 8133: 2000, or FIM FRHPhe-02 standard. All helmets used in road racing and flat track must have been manufactured within the prior 60 months of the date of competition and meet Snell (or equivalent) standard at the time of manufacture. Only OEM chin-strap fasteners may be used (no aftermarket quick-release fasteners are allowed). This change is provisional for the 2022 season only. All helmets must be intact, and no modification may be made to their construction that alters the helmet from the condition it was tested and approved. The helmet is made to provide protection and is not a platform to attach foreign objects. Cameras or other accessories are NOT permitted to be attached to the rider’s helmet.
Helmets worn in vintage, and post vintage motocross, next gen motocross and cross county may be open[1]or must be full-face type and certified by the manufacturer by having a sticker affixed to the helmet stating the helmet meets or exceeds U.S. Department of Transportation (DOT) FMVSS 218 and at least one of the following standards:
U.S. Department of Transportation (DOT) FMVSS 218; Snell M2010 2020, Snell M2025; Europe’s ECE 22.05 ‘P’ (accepted through 2027), or ECE 22.06 ‘P’, ‘NP’ or ‘J’; or Japan’s JIS T 8133:2007. It is recommended that motocross and cross country helmets be removed from service after five years from date of manufacture; helmets greater than five years old – but no more than 10 years old – may be used at the discretion of the Tech Inspector. Only OEM chin-strap fasteners may be used. Helmets worn in vintage trials may be half, open or full-face type and must meet or exceed U.S. Department of Transportation (DOT) motorcycle standards or equivalent international standards.
All helmets are subject to inspection by AHRMA competition officials to ensure compliance. This inspection does not warrant the condition of a participant’s helmet.
It is the responsibility of the participant to ensure his/her their helmet is in compliance with AHRMA requirements. Riders are prohibited from using damaged helmets. If there is any question regarding the condition of a helmet, technical inspection will consult with the Road Race Referee, Road Race Director, or Off-road Race Director on final determination on acceptance for use in competition. Their decision is final and not subject to appeal.
Rule Change Rationale: Submitted on behalf of the AHRMA Safety Committee: The current helmet requirements are outdated and not in line current certifications or with other racing sanctioning bodies. There are references to approvals that were supposed to only apply to 2022 race season. The revised helmet requirements were unanimously approved by the AHRMA Safety Committee. The revision are in line with up to date with the national and international requirements. Overall these changes help reduce risk to the organization. (Bill Gillis, Member #8747)
Committee Recommendation: Accept (Unanimous)
Committee Discussion: Safety committee has done the research with other organizations, including FIM, as generally accepted practices. Additionally, NJ has Snell 2020 requirement for racing helmets. We need to be aligned with other organizations. Shouldn’t be an RCP in the future – should be a safety committee responsibility to update.
Board Discussion: Moving forward, it’s an update which will be required in the handbook if there’s any change that the industry standard as a safety item. It was agreed that it’s more housekeeping rather than a rule change and will be the responsibility of the safety committee to update in the future and not part of the RCP process.

General Road Racing Rules
Entry ID 14403 9.6.5
9.6.5 Points will be awarded at all roadraces according to the following schedule. National championship events also award regional-championship points for the region in which the event takes place.
National Series awards are based on a rider’s best finishes in one-half of the total number of races up to 20, in the series, rounded up to the next whole number if necessary (e.g., in a 19-race series, a rider’s 10 best finishes count). A rider must score points in at least two events to be eligible for National series awards. Criteria for Regional Series Awards will be defined and published prior to the first event of the year. Yearly schedule changes to events and locations may change the regional series criteria. Year-end scoring ties will be broken by the greatest number of first-place finishes, then second-place finishes, third place, etc. within the best finishes. If still tied, the position will be awarded to the rider with the better results in any head-to-head, on-track meetings. In the event of an absolute tie, the oldest rider wins.
Committee Recommendation: Accept (Unanimous)
Committee Discussion: Due to the magnitude of points awarded, it never happens, never seen a decision made by this, basically housekeeping.
Board Discussion: Motion to vote WP, second JB
July Board: yes (11 yes / 0 no)
Vintage Road Racing
Entry ID 14374 10.3.1 A i
Maximum rim width: front, 2.5 inches (WM-4); rear, 3.0 3.5 inches (WM-56), except H-D XR750s, which are permitted to use a WM6 (3.5 inches) when fitted with original Morris Magnesium wheels. No Astralite wheels. (John Turner, Member #62)
Rule Change Rationale:
There are several reasons for this rule proposal to be approved.
- If you try and buy a new mag rear wheel to build a bike, the smallest you can buy is a 5”. This is copied from the Marvic website. Rear3,50″ x 18″ – 4,00 “x 18″ – 4,50″ x 18″. They do not have an option to buy a 3” rear.
- The rule for Harley also said “when fitted with original Morris Mag wheels” I don’t know about you, but I would not feel confident on running a 50 year old Magnesium wheel.
- The HD bikes are allowed to run a 5″ rear now, so this rule change would put all bikes on a level playing field and make it easier to buy wheels.
- Giving other bikes than the HD an extra 1/2” rear rim width is not going to make a bike demonstrably
Link to website to view. Marvic website
Committee Recommendation: Reject (Unanimous)
Committee Rationale/Discussion: The committee agreed that a half inch wheel width increase would potentially create an additional advantage for the higher power machines in the class. We also believed it could cause the current competing members to feel the need to upgrade their already legal machines, at significant cost, for minimal or possibly negative effects.

Entry ID 14380 10.6.3
10.6.3 Eligible Novice Historic Production Heavyweight Motorcycles include:
…
Norton, all 650/750 (except short stroke), 830cc twin-cylinder, OHV-pushrod
…
(David Henderson, Member #2014212)
Rule Change Rationale:
The “classic” time of Production Racing motorcycles is the 1969 – 1978 years, as the class allows. This was the time of Ray Pickrell, Percy Tait, Peter Williams, Paul Smart, Dave Degans, Godier/Genoud and other famous names. Production races during this time showed that the Norton 830cc twin-cylinder, overhead-valve pushror engined racers had no performance advantage over the Honda 4, non-Desmo Ducatis, Kawasaki 500, or Triumph-BSA triple cylinder motorcycles – or even the 750 Norton racers (as allowed in the class).
Including this engine in the class would offer a racing opportunity for Novice riders with a Norton motorcycle of this engine type, allowing the class to fully represent the Classic Production entries of the period.
Committee Recommendation: Reject (Unanimous)
Committee Rationale/Discussion: Production racer was never offered as an 830cc model. Only 750cc in 1970 and 1971. Novice Historic Production Heavyweight is also limited to 750cc.
Board Discussion: Motion to vote GT, second TT
July Board: no (0 yes / 9 no / 2 abstain JB, WP)
Entry ID 14381 10.6.4 h
(h) FAIRINGS AND BODYWORK: Fairings of any type are not allowed, except OEM type as original factory fit. Gas tank, seat and fenders must be OEM equipment or period replacements. No modern “GSXR-style” bodywork will be allowed. (David Henderson, Member #2014212)
Rule Change Rationale:
Allowing the use of original factory-fit fairings will more closely represent the “Golden Age” of Production Racing in the 1969 – 1978 racing period; the exact time period as allowed for motorcycle in the “Historic Production” class. This rule change will show motorcycles visually as they appeared on tracks at this time and will allow owners of interesting “genuine vintage” motorcycles (such as Norton Production Racer and Velocette Thruxton, etc. ) to race in this class.
Speeds reached by Production Racing motorcycles are modest enough that use of a fairing will not significantly increase the speed or lap times of the motorcycle involved.
Committee Recommendation: Accept (Unanimous)
Committee Rationale/Discussion: The committee feels that OEM equipped fairings are keeping within the intended purpose of the class. The change would also the allow Norton 1970/1971 750cc Production Racer.
Board Discussion: Motion to vote WP, second BR
July Board: yes (8 yes / 1 no GT / 2 abstain WP, JB)
Entry ID 14387 10.6 NOVICE HISTORIC PRODUCTION
Novice Historic Production is open to (1st paragraph unchanged)
…
All engine and transmission components and assemblies must maintain OEM dimensions and limits. Aftermarket parts are allowed only if they are a direct replacement for the originals. Modifications for reliability (e.g., starter removal or ignition replacement) or to resolve non-performance issues (e.g., cam chain tension or oil pressure) are permitted. Classes are Lightweight (four-strokes up to 500cc, 250cc two-strokes and specific 350cc two-strokes listed with an asterisk (*) below) and Heavyweight (four-strokes up to 750cc, except as specifically allowed, and 350-500cc two-strokes); three- or four-cylinder DOHC machines are not allowed. (David Henderson, Member #2014212)
Rule Change Rationale: This request is to allow the allowance of slightly larger twin-cylinder, overhead-valve pushrod engines in the heavyweight class, as requested in detail in my Rule Change Request 14380.
Committee Recommendation: Reject (Unanimous)
Committee Rationale/Discussion: This RCP is a “housekeeping” proposal tied to Entry ID: 14380. The committee believes the original 750cc limit was intentional to keep power levels down to a reasonable level for the novice class.
Board Discussion: Motion to vote WP, second JB
July Board: no (0 yes, 10 no, 1 abstain JB)
Entry ID 14412 10.4.3 CLASSIC SIXTIES
Among the eligible machines are:
…
- BSA B50 as as either a single “works” or replica and like design
…
(John Rickard, Member #2181)
Rule Change Rationale: This rule change’s purpose is to get more vintage bikes on the track.
B50 road race bikes are not being raced. The BSA B50 is legal for 500 Premier but racers haven’t entered them in that class. Perhaps B50s will be raced in Classic 60s.
Committee Recommendation: Accept (Unanimous)
Committee Rationale/Discussion: The committee feels that the BSA B50 would be an appropriate fit for the class when outfitted in period GP and Clubman trim. A suggestion from the committee was to allow the B50 with a minimum dry weight of 270lbs in an attempt to keep efforts aimed at maintaining period appearance and avoid a stripped down lightweight racer.
Board Discussion: This proposal intended to add the BSA B50 to the classic 60s class. While the committee recommended acceptance, they suggested a 270lb minimum weight limit to prevent stripped-down, lightweight configurations. Participants debated the enforceability of this weight limit in the current ruleset, eventually deciding that without specific weight verbiage in the proposal, they would vote on the submission as written.
Motion to vote GT, second JO
July Board: no (1 accept TT, 10 reject)
Entry ID 14437 10.11 Moto LeMans
Moto LeMans: Any bike eligible for Formula 125 (10.3.4), 250 Grand Prix (10.2.4), 200 Grand Prix Plus (10.2.5). Eligible bikes include CB/CL160,CB/CL175 all years. No SL175 frames to be used. All stock engine components must be used or accurate replacements. Any combination of Honda engine parts can be used, 160cc engines can be unfitted to 175 spec including 5 speed upgrade. Twin leading shoe front brake only with max size no larger than cb160 brake. 24mm carb max size. Any ignition may be used. Any exhaust may be used, mufflers required. Must use steel fuel tank. No oxygenated fuel. Entry fee shall be the same as all other vintage road race classes. The start shall be a “LeMans” push start of the type previously used for CB160. (Rob Hall, Member #9219)
Rule Change Rationale: We would like to create a cheaper and closer to spec class for these bikes in hopes to bring back the numbers we had when bikes weren’t so cost prohibitive to build. This is a very fun class that will become more fun when we are all on very equal bikes!
Committee Recommendation: Reject (Unanimous)
Committee Rationale/Discussion: The committee fears this risks pulling eligible and currently competeing members out of the class in hopes that they may be replaced by bikes to be built for the class is a risk. The committee would like to add that they support the idea of a cost effective racing but would like to see more than one make/model represented.
Board Discussion: The group discussed a proposal to return the Moto LeMans class to a stock 160/175 model limit. The committee recommended rejection to avoid losing current participants, but Tim Terrell argued that the change would bring back a budget-friendly, spirit-aligned class and most of the current participants have expressed support in favor of this proposal.

Vintage Superbike
Entry ID 14335 10.8.3 (Vintage SB Table)
LIGHTWEIGHT Pushrod twin BMW 650 (Mark Morrison Member #2010668)
Rule Change Rationale:
I would like AHRMA to consider a rule change proposal removing the BMW 650 from the list of approved Vintage Light Weight Superbikes in rule 10.8.3. I believe they have an unfair advantage and are a better fit for the Vintage Middle Weight class. I offer the following reasons:
- First the BMW’s are between 60cc to 300cc larger engine displacement than the other approved
- If you look at the lap times the BMW’s consistently turned at races they are 5 to 20 seconds a lap faster than the other makes (see attached spreadsheet). While some of their advantage can be marked down to rider ability the significant cc size allowance doesn’t
- Their times have been well within the competitive lap times turned by the Vintage Middle Weight bikes (see attached spreadsheet). In most cases those lap times would have resulted in podiums and possible wins. The margin of lap times would be closer than that in the Vintage Light Weight class.
Committee Recommendation: Reject (Unanimous)
Committee Rationale/Discussion: There have only been 5 champs on BMW in 25 years, most have won on Honda Ascots or Suzuki GS450. Probably the most balanced class in AHRMA. If you are fast you can win on any legal bike.
a. The BMW pushrod R65 has been eligible for VSBLW since the creation of the class, along with the Moto Guzzi V65. These bikes are popular choices for this class.
b. A properly tuned machine (SR500, Honda 400F, Honda Ascot, Suzuki GS) can outperform the BMW. This has been proven in the past.
c. Raced a BMW R65 in the past and found it to be very balanced against the other machines in the class.
d. Finally, if the BMW R65 *was* deemed to be significantly faster than other models in the class, the handbook states:
10.8.4 All classes listed above are based upon an index of performance. If any model proves to be significantly faster than other models in its class, its performance may be restricted by limiting carburetor size, etc. If any model proves to be significantly slower than others in its class, it may be moved down to the next lower class.

Among the eligible machines are:
- 1998-2003 Aprilia RSV Mille, Mille R, Mille SP and Replicas (Haga and Edwards). Bikes are limited to first generation Mille
- 1987 – 2002 Ducati 851, 888 with 996 engine; Ducati 916, 916SP, 916 Corsa and 916R; Ducati 996, 996S, 996SPS, All Ducati motorcycles must use Desmoquattro engines only, no Testastretta engines, heads, or components. Ducati 748, 748R, 748RS may compete, provided engine capacity has been increased by modifying bore and/or stroke to a maximum of 996cc.
- 1994-1995 Honda RC45, 2000-2006 RC51 SP1, RC51 SP2
- 1999-2004 MV Agusta F4 750 ORO, S, S 1+1, SPR, 750cc models

- 1999 Yamaha R7, 1993-1998 YZF750R, YZF750SP
Approved motorcycles must have been available for sale in North America. (John Turner, Member #62)
Rule Change Rationale: This is more of a simple house keeping modification. I just added years to the rulebook model listings to make it simpler for people to understand. No new years or models were added.
Committee Recommendation: Accept (Unanimous)
Committee Rationale/Discussion: This was housekeeping adding years of motorcycles to the rulebook.

(Michael Platt, Member #1012553)
Rule Change Rationale: Trying to find a place to put newer common 600cc bikes without creating a whole new race class in AHRMA. These bikes will be at a slight disadvantage in this class but it will give them a place to race and help increase grid size and membership in AHRMA
Committee Recommendation: Accept (Unanimous)
Committee Rationale/Discussion: This is to add older 600’s cc bikes to the current 750cc class. It will not upset the class and should add some more machines and entries.

Entry ID 14370 9.8.1 k (3)
- OEM airbox systems may be modified or removed. Gen 1 SV650s (1999-2002) may use flat slide carburetors. Air filters may be replaced. Airbox drains must be sealed. Crankcase vent hose must remain routed to the airbox. Crankcase breathers may be modified or replaced. If the airbox is removed, the crankcase vent must be routed to a 120 ounce, leakproof catch can. (Kevin Dinsmoor, Member #1013424)
Rule Change Rationale: A rule that allows removal of air box but not specifically a modification is ambiguous. I see many(nearly all) Supersport bikes with modified air boxes. If they can be removed entirely, the mind set is they can be modified. This would clear that up. Further, if the R7 is allowed in SOT3, it needs to have the air boxes modified, they simply wont run proper at road racing speeds

All classes may be run together and scored separately as determined by the number of entries and track conditions. See section 9.8 for additional mechanical requirements:
b) SOUND OF THUNDER 2 (SoT2): Any AHRMA Sound of Singles or Motard machine; liquid-cooled twins to 900cc; unlimited air-cooled twins; triples up to765cc; 4 stroke liquid cooled 4 cylinder up to 636cc, and two-strokes to 250cc are allowed. (John Turner, Member #62)
Rule Change Rationale:
Hello,
I am the chairman of the Next Gen Rules committee. I have received at least 12 inquires this past 1/2 season about a place in AHRMA for modern 600cc motorcycles. Right now, we do not have a place for them to race. Of the 12 recent inquires, 8 were just before the West coast races. I had to tell these people, unfortunately, we do not have a spot for your bike. Most of these 600cc bikes are no longer produced by the manufacturers. The supersport category is absolutely a Historic class, so one could make an argument with most of the manufacturers not making these bikes anymore, they are Historic.
What this rule change will do is bring in new bikes and Members into an already modern class. In researching these bikes and this class, I found that Sound of Thunder 2 almost mirrored the Moto America Supersport class. Many of the bikes that are eligible in our SOT2 class, except the 4 cylinder 600 machines, are eligible in the MA Supersport class. Moto America shoots for around 130hp for their class, which is what many of the bikes in this class currently produce. The Triumph 765 Moto 2 is 130 hp, Ducati V2 120 hp, a Moto Corse 1200 Air Cooled Ducati Twin is in the 120-140 hp range. Theses new 600cc 4 cylinder machines will not dominate the class, they are all in the same hp range too. This addition will most likely bring in more bikes and MEMBERS which is most important for the long term continuation of the club. The MAIN advantage of this is, it does not add another class to our already bloated schedule. It puts these machines into a place where all will be competitive. It will not outclass what is already winning the class.
I will be making 3 rules proposals to possible change the class. 1, add 4 cylinder 600cc motorcycles, increase twin and triple cc’s. if all the=ree are added, the class will be very similar to MA supersport rules.
Committee Recommendation: Accept (3-1)
Committee Rationale/Discussion: Need a place in AHRMA
Board Discussion: Discussion regarding the current size of the class, and unintended consequences of adding potentially another 10-15 bikes at an event like Barber which already requires SOT2 to run by itself. These bikes already have a number of other organizations they can race with.

Hello,
(I will be making 3 rules proposals to possibly change the class. 1, add 4 cylinder 600cc motorcycles, 2, increase twins and triple cc’s. If all three are adopted, the class will be very similar to MA supersport rules, which it is now already.
I’m using the same rationale for each proposal because I was asked to split them up. This one is to increase the twins cc from 900cc to 955cc. This will allow all Ducati V2 machines in this class.)

I’m using the same rationale for each proposal because I was asked to split them up. This will allow up to 890cc triples into the class. The Yamaha R9 would be allowed to compete in this class.)
I am the chairman of the Next Gen Rules committee. I have received at least 12 inquires this past 1/2 season about a place in AHRMA for modern 600cc motorcycles. Right now, we do not have a place for them to race. Of the 12 recent inquires, 8 were just before the West coast races. I had to tell these people, unfortunately, we do not have a spot for your bike. Most of these 600cc bikes are no longer produced by the manufacturers. The supersport category is absolutely a Historic class, so one could make an argument with most of the manufacturers not making these bikes anymore, they are Historic.
What this rule change will do is bring in new bikes and Members into an already modern class. In researching these bikes and this class, I found that Sound of Thunder 2 almost mirrored the Moto America Supersport class. Many of the bikes that are eligible in our SOT2 class, except the 4 cylinder 600 machines, are eligible in the MA Supersport class. Moto America shoots for around 130hp for their class, which is what many of the bikes in this class currently produce. The Triumph 765 Moto 2 is 130 hp, Ducati V2 120 hp, a Moto Corse 1200 Air Cooled Ducati Twin is in the 120-140 hp range. Theses new 600cc 4 cylinder machines will not dominate the class, they are all in the same hp range too. This addition will most likely bring in more bikes and MEMBERS which is most important for the long term continuation of the club. The MAIN advantage of this is, it does not add another class to our already bloated schedule. It puts these machines into a place where all will be competitive. It will not outclass what is already winning the class.

SOUND OF THUNDER 4 (SoT4): Any single or twin cylinder four-stroke production motorcycle up to 400cc 500cc sold in the U.S. with a street-legal VIN. The Ninja 400 All twin cylinder machines over 398cc displacement are is limited to Supersport specifications (see 9.8.1) otherwise it they must compete in SOT3. (Daniel May, Member #11215)
Rule Change Rationale: Multiple manufactures have already introduced new models in the “sub-500” sport bike category, and most others are planning machines in this segment in the near future. The AHRMA SOT4 class is a great way to get young riders interested in racing, and gives AHRMA an opportunity to introduce them to vintage bikes. Unlike our vintage classes, we must evolve our modern classes to remain current with the market.

SOUND OF THUNDER 3 (SoT3): Harley-Davidson XR1200, pushrod OHV twin cylinder machines to 1000cc, OHC two- or three-valve twins to 805cc, SOHC liquid cooled V-twins up to 750cc (plus overbore), OHC liquid-cooled four-valve twins to 650cc. Pushrod OHV machines over 900cc must run under Supersport specifications (see (9.8.1). Suzuki SV650 except carbureted GEN 1, Buell XB9R Ducati 800SS, 750SSie and Monsters limited to Supersport specifications (see 9.8.1); otherwise, must compete in SoT2. GEN 1 Suzuki SV650 may be equipped with Suzuki suspension from other near-year GSXR. Thruxton Cup Challenge eligible machines may compete (see 10.14). Ducatis up to 750cc originally fitted with carburetors (e.g., 1991 1985-98 750 Supersports , Sports, F1’s, Monsters) must meet the mechanical requirements in 9.8 a) through m) only, with the additional requirement being they must use OEM or aftermarket carburetors. Kawasaki Ninja 650, 650R & Z650RS must meet mechanical requirements in 9.8 a) through m) only, with the additional requirement they must retain OEM bore and H-D XR1200 and Ducatis up to 805cc originally fitted with fuel injection (e.g., 750SSie, 800SS) must run under Supersport specifications (see 9.8.1). Machines originally equipped with 18” wheels may convert to 17” wheels. Yamaha R7 & FZ07 allowed on performance index under Supersport specifications with exception of airbox removal or modifications allowed. (Kevin Dinsmoor, Member #1013424)
Rule Change Rationale: Class needed some clean up of language. Changes include adding 1985-1990 production Ducatis up to 750cc which currently have no class other than SOT2 and are not an advantage in the SOT3 class. Also, addition of Yamaha R7 and FZ07 as they are not competitive in SOT2 at all and their performance index puts them comparable to the SV650 Suzuki. It will result in racers with R7’s having a place to race their bikes competitively.

The Ninja 400 is limited to Supersport specifications (see 9.8.1) otherwise it must compete in SOT3. 8.5 BATTLE OF TWINS (Bill Gillis, Member #8747)
Rule Change Rationale: The speed differential between modern middleweight twins and SOS1 single cylinder machines is too great. This induces an unnecessary and avoidable safety risk. Having slower single cylinder machines in SOT2 also creates a quality of experience challenge for SOT2 riders. When SOS1 machines are gridded near the front of the SOT2 grid, it makes the most dangerous time of any race, more dangerous. The SOS1 machines are very comparable in HP and performance to the SOT3 machines. For overall and grid safety I believe this change makes responsible sense.
Committee Recommendation: Accept (Unanimouos)
Committee Rationale/Discussion: Safety issue of singles in SOT2
Board Discussion: The board discussed the phrasing of rules regarding moving Sound of Singles machines, specifically noting concerns about how the Motard class was handled and potential impacts on SOT3.

700 CHALLENGE: A separately scored class that grids and runs concurrently on track with Sound of Thunder 3 (SoT3).
General eligibility: four-stroke two-cylinder machines up to 799cc; four-stroke triples up to 660cc; four-stroke singles up to 700cc.
Specifically recognized machines and preparation allowances:
- Aprilia RS 660 — prepared to AHRMA Supersport specifications (see 8.1).
- Triumph Daytona 660 — prepared to AHRMA Supersport specifications (see 8.1).
- Yamaha YZF-R7 — Supersport specifications (see 8.1) with limited top-end engine modifications such as airbox and high-compression pistons.
- Suzuki SV650 — bored to a maximum displacement of 700cc, prepared to AHRMA Superbike specifications (see 9.8.2).
- Kawasaki Ninja 650 — bored to a maximum displacement of 700cc, prepared to AHRMA Superbike specifications (see 9.8.2).
- Kramer
Machines legal for Sound of Thunder 3 (see 8.4.c and 10.12.1.c) or Sound of Thunder 4 (see 8.4.d and 10.12.1.d) are also eligible to compete in 700 Challenge. (Tres Millard, #2012439)
Rule Change Rationale:
The 700 Challenge fills a gap in AHRMA’s class structure for accessible, modern middleweight twins, small triples, and middleweight singles that do not fit cleanly into existing Sound of Thunder classes. Machines such as the Aprilia RS 660, Triumph Daytona 660, Yamaha YZF-R7, big-bore Suzuki SV650 and Kawasaki Ninja 650, and the Kramer 690 have an active grassroots racing community, are widely available, and are comparatively affordable to campaign. Today, riders bringing these bikes to AHRMA have no natural home class.
Running the class concurrently on track with SoT3 — but scoring it separately and prohibiting cross-entry — adds a new entry pathway without requiring an additional race slot in an already-full
weekend schedule. The one-way eligibility design protects competitive balance in SoT3 (which keeps its existing field rules unchanged) while giving SoT3 and SoT4 competitors the option to run up for a second result.
Anticipated benefits:
- Attracts contemporary club-racing riders to AHRMA who currently have no class fit for modern middleweight twins, small triples, or middleweight singles.
- Grows grid size at events at minimal organizational cost (shared grid with SoT3, no new race slot).
- Provides a natural development class — riders can step up from SoT4 to 700 Challenge and then on to SoT3 or above as skills and budget allow.
Preserves the integrity of the existing SoT3 class by keeping purpose-built 700 Challenge machines out of it.

Vintage Motocross
Entry ID 14408 Section 11
Note: A 10-year moratorium on adding new vintage motocross classes is in effect beginning in 2018 (Bob Bean, Member #10830)
Rule Change Rationale:
AHRMA needs to either remove this rule or suspend it to allow for changes in the age groups.. As members are getting older the average age of off road racers has risen. The age groups need to be changed to reflect on this aging demographics.
Also as members age, things start changing quicker than 10 year periods. There is a big difference in aging going from 40 to 5o or going from 60 to 70 or 70 to 80. In many other sports, running, bicycling etc, the age groups move in 5 year periods.
In going thru the numbers, we now know that there are enough members to justify adding a 76+ class to the age groups. (does not have to be all 3 ratings, Expert, Intermediate and Novice.. ) I seriously doubt any 76 + Novices will happen, so could be just one.
Here are the numbers for age groups of AHRMA off road members currently. Age
60-64 215 members
65 51 members
66-69 292 members
70-74 180 members
75 11 members
76-79 37 members
80+ 34 members
As we know, our new members numbers are not growing very well. How many members have we lost that aged out, feeling they are too slow for the new young 70 year olds. These are founding members who have supported AHRMA for years. We owe it to them to provide a class for them to compete in with age appropriate other members.. I will be asking the Trustees to suspend this 10 year moratorium to allow a new 76+ class for these AHRMA members… We cant afford to lose more members!
Committee Recommendation: Reject (Unanimous)
Committee Rationale/Discussion: It is the committees opinion that this rule should stay in place because we think that it will discourage most rule proposals that are not thought through. And as this proposal has shown, all one would have to do is propose the removal of this rule if one wants to propose a new class. We have yet to see a rules proposal that would warrant the removal of this rule.

11.1.20 76+: Riders aged 76 and older on any size or type of eligible vintage machine. Open skill level, to be ran with novice group only due to safety concerns.(Bob Bean, Member #10830)
Rule Change Rationale: A strong suggestion per the off road director and others is to run this class with others of like speed. NEVER with 40+ , 50+ or other Expert classes.
Committee Recommendation: Reject (Unanimous)
Committee Rationale/Discussion: We feel this rule lacks safety precautions. As it is written, there would be Experts riding with Novices and bikes that could be many CC’s apart. For example; Robert Poole (an Expert) could be riding his BSA 650CC next to a Novice rider who may be riding a 100 CC machine. The horsepower and skill difference on the same track at the same time is unacceptable in my mind. Even if this rule were to be re-written to create its own gate for each skill set, we do not have enough time in the day on the West Coast to allow for more classes. This proposal can be done at any regional race as well as a national (with proper approval), there wouldn’t be any points awarded but at least the class could be run to fins out how many riders may be interested.
Board Discussion: After 14408 was rejected the board agreed no vote was needed for this proposal since it would result in a new class before the moratorium expires and discussed alternative ways to honor riders over 76 years of age without adding new classes.

12.1.2 11.1.22 Historic 125: Certain 88-125cc machines built… (through list of eligible Historic Class motorcycles). (Jim Laird, Member #19621)
Rule Change Rationale:
This rule change, which is actually more of a race day event schedule change will allow enthusiasts and members who do not race vintage classes to participate on the Vintage Classes race event day.
It will bolster attendance, participation and revenue by offering another class to fill out the lesser attended Vintage event day, while at the same time relieving the Post Vintage day/ event schedule.
Committee Recommendation: Reject (Unanimous)
Committee Rationale/Discussion: We feel that this rule is only the tip of the ice berg. If we let 125 in to the vintage days it will set a president on allowing NON VINTAGE motorcycles in which will create more classes which leads to longer days. In the rational the submitter says “It will bolster attendance, participation and revenue by offering another class to fill out the lesser attended Vintage event day, while at the same time relieving the Post Vintage day/ event schedule.” This rational does not work on the West Coast. The only day that needs bolstering is the PV day. This is similar in the middle of the country I am told by one of my committee members. He says the days are about even.

Committee Recommendation: Accept (3-1)
Committee Rationale/Discussion: accommodate member aging and ability level acquity changes, providing an opportunity to enjoy the sport in later life.

Entry ID 14449 12.5 d)
12.5 d) Carburetors: Period-type carburetors are strongly encouraged. Period flat-slide carbs are allowed on historic and Gran Prix class motorcycles. Examples include Lake, Lectron, Posa and other period-type flat-slides. Active accelerator- pump-equipped carburetors are allowed only on Ultima – class motorcycles, all other; must be disconnected or removed, even if OEM-equipped. Dell”Orto accelerator pump carburetors are allowed in the Historic and Gran Prix classes only if the accelerator pump mechanism is disconnected or removed. Period Modern flat-slide Mikuni TM carburetors and all CV carburetors are allowed only on Ultima class motorcycles. Mikuni TMX and Keihin PJ and PWK flat-slide carburetors are not permitted. Modern D-shape-slide or similar equivalent aftermarket OKO are not allowed in AHRMA Post vintage off-road competition. (Bob Bean, Member #10830)
Rule Change Rationale:
This rule should be changed as Flat slide carbs came on several different models built in 82 and 83, during the Ultima model years. As carbs wear out and a lot of those old carbs are no longer available, a wider choice is needed. You can buy a modern flat slide (Chinese copy) for as low as $50 and they perform no better than the others. Changing the carbs just moves the powerband around. Careful jetting can provide better results on old carbs if not worn out.
Committee Recommendation: Reject (Unanimous)
Committee Rationale/Discussion: round slide carbs are available (Mikuni, Keihin, or Chinese copies), and the flat side carbs have a distinct advantage over round side carbs. As proposed, especially this portion he changed could be interpreted as opening the door for Modern D-shape-slide or similar equivalent aftermarket carbs in all post-vintage racing.

Observed Trials
Entry ID 14383 13.1.11
13.1.11 AIR COOLED MONO (ACM) with drum brakes only. Trials machines manufactured just after the twin shock era, but before significant performance advances were introduced to trials bike technology. Typically, mid-to-late 1980s models. (Scott Stewart, Member #3182)
Rule Change Rationale: AHRMA Road Racing and Next Gen Moto Cross have machine classes that include bikes with disc brakes.Why should Observed Trials be any different ? The 3 year moratorium for no new classes in Observed trials is over at the start of the 2027. In the past 5 years (since 2021) only Yamaha motorcycles have competed in the Air Cooled Mono Class.That’s right, just 1 steel horse/1 motorcycle brand in the class! This is probably the only place in all of AHRMA that this situation occurs. Does anyone enjoy spectating a motorcycle race where there is only 1 motorcycle manufacturer racing? AHRMA would gain new members, riders, and motorcycles if they would allow the other 90% of the the Air Cooled Mono Class to compete. It is unfortunate to think that these historical motorcycles were excluded because of their hydraulic disc brakes. It is disingenuous and petty to not right this wrong. I am not alone in this opinion, and AHRMA needs to respect all of its members, not just a select few.
Committee Recommendation: Reject (Unanimous)
Committee Rationale/Discussion: Allowing disc brakes will open AHRMA trials classes to much more modern technology.

July Board: no (0 yes / 10 no / 1 abstain TT)
Entry ID 14431 SECTION 13 OBSERVED TRIALS
NOTE: A 3-year moratorium on adding new observed trials classes is in effect, beginning in 2024 2027. (Debbie Poole, Memer #542)
Rule Change Rationale: Examining the success of AHRMA’s newest trials class, Air Cooled Mono, illustrates the validity of continuing the moratorium on new trials classes, specifically for more modern machines.
The Air Cooled Mono class (typically mind-to-late 1980’s machines) was added provisionally in 2021. For purposes of this proposal, results for 2021 and 2022 are not used, due to the negative effect COVID had on event participation.
What is discovered in the accompanying documents is that in 2023, 2024 and 2025, the Air Cooled Mono Class participation has been marginal at best. Please see documentation for more details, but in summary over these 3 years the class saw 16, 23 and 18 entries respectively, but more importantly these entries consisted of very few individual riders:
2023 7 riders
2024 10 riders
2025 11 riders
Further, if you examine the individual riders over these three years, it is shown that the participants are limited to the same 8-9 riders nationwide. The class is struggling. The class is not growing. To add another Trials class and more modern machines would likely be unsuccessful, and would further dilute entries for the existing Air Cooled Mono class.
Committee Recommendation: Accept (Unanimous)
Committee Rationale/Discussion: Committee feels the current Air Cooled Mono class is the most modern class needed at this time

13.1.10 VINTAGE YOUTH CLASSES: AHRMA Youth Classes are open to any rider through 14 years old. Skill levels are: Youth A riding the “2” line, Youth B riding the “3” line, and Youth C riding the “4” line. There is no minimum age requirement, just an ability to ride the loop and attempt the sections.
Eligible machines include any air-cooled, twin shock, drum brake motorcycle as manufactured of 125cc 175cc or less. Examples include 1974-1975 Yamaha TY80s, 125’s, or 175’s, some European Mini Trials bikes, and “homebuilt” specials using period correct components and techniques. (Wes Poole, Member #1012195)
Rule Change Rationale: The 125cc limit has discouraged a number of younger riders from entering the Youth class. Honda TL 125’s are about the only option, aside from TY 80’s which most kids have outgrown by the age of 9. The Honda TL 125’s are also heavy when compared to the lighter two strokes, such as the TY175. The Montesa Cota 125 and Yamaha TY 125 are good for kids, but are extremely rare and hard to find.

See attached marked up table. (Sean Chase, Member #2010316)
Rule Change Rationale: Several expert premier class riders in the Northwest routinely post single digit scores on the expert lines. This addition of a Master level would provide expert premier class riders an ongoing challenge and it would open up the field for upcoming expert riders.

The committee would prefer one 76+ class for all riders run in the first hour, the Vintage event, as this potential rider/motorcycle combination would not upset the balance of the event.
Board Discussion: Discussion focused on whether this would create an open skill level that would unfairly disadvantage novice riders, as well as the safety implications of age-based classes in cross country versus motocross. Proponents argued it was a way to show appreciation for older riders who have been part of the program for a long time, while others questioned the logic of the 76 age cutoff and the potential for a proliferation of age-based classes.

e) HISTORIC 200: Historic-class machines manufactured as 88-200cc. Includes first generation twin-shock Honda XL/XR 185 and 200
…
Each of the following classes is further divided into Novice, Intermediate and Expert skill-levels.
a)HISTORIC 200: Historic-class machines manufactured as 88-200cc. Includes first generation twin-shock Honda XL/XR 185 and 200
… (Jim Laird, Member #19621)
Rule Change Rationale: This rule change can and should include moving the Historic 200 Motocross Class to also run with the Vintage Classes, on whichever day that event is run (Saturday or Sunday). This change will bolster the Vintage Event racer entry participation and revenues for AHRMA, and also allow participants the opportunity to race their Historic Class bike on one day and also then participate in other PV Classes on the second day rather than forfeit their PV Classes in order to only being limited to running Historic Class on the PV event day.
This change will also encourage younger racers to participate by allowing them to ride a ‘slightly more modern’ and relevant motorcycle than their grandfather is racing in his 60’s. Truthfully, Historic is the pinnnacle of vintage capturing a unique era of innovation that was industry impacting, but in no way advanced or improved enough to give Historic Class bikes a significant advantage over Vintage Class machines. In some ways, the Historic Class machines are inferior because parts are extremely rare and expensive. This change allows PV racers to run the PV race, but enjoy racing their 1975-1977 ‘childhood vintage bike’. Lastly, I can convince younger people to race a Historic bike easier than trying to convince them to invest in an ‘ANTIQUE’ bike that AHRMA titles ‘Vintage’.
Committee Recommendation: Reject (Unanimous)
Committee Rationale/Discussion: The committee rejects this proposal. We have 5 riders that have ridden both Vintage and Historic classes at National events this year. The Historic classes are the “bump up” classes for a Vintage rider to enter the Post Vintage event. While ways to increase the participation in the first event at a Cross Country is an open question, the inclusion of the Historic 9 inch travel, more powerful motorcycles, into the Vintage, 4 inch travel, event would upset the balance of the event. The Historic machines come from an era after the Vintage machines and do not belong in the Vintage event. Also, moving the Historic 200 class and not the Historic Open class to the Vintage event is not correct.

I have gathered additional data to help us make the right decision regarding changing the SOT4 displacement limit to 500cc.
In stock configuration, the peak performance difference between the Ninja 500 and Ninja 400 is 3 hp. However, the key difference lies in the power curve: the Ninja 500 makes 9 hp more than the Ninja 400 at 8,000 RPM. This gap demonstrates that if riders utilize the tuning options allowed under Supersport regulations, the Ninja 500 has the potential to make significantly more power than the Ninja 400.
Furthermore, we must consider grid health. While the KTM 390, Yamaha R3, and Ninja 300 are rarely podium contenders, they remain a vital part of the class. So far this year (including GingerMan), these three models accounted for 54 out of 119 total SOT4 entries.
Before opening the class to 500cc machines, we must carefully evaluate the impact on these riders. In my view, the only fair way to increase the SOT4 limit to 500cc is to implement strict performance restrictions on any motorcycle exceeding 400cc.
Dear Safety committee, BOT and members. I would like to address the changes in the Helmet Safety proposal on entry # 14429 3.3.14. Lets start with some facts about Helmet safety and certifications levels. Full face Helmuts DO NOT in general have a “higher are safer rating or certification” then open face Helmets. PERIOD.( if your referring to approved Helmets in the rationale statement, SNELL 2025, ECE 22.05, ECE 22.06)( Excluding High End Professional Units most don”t utilize in ARHMA) Those Helmet specialized tests are designed to evaluate protecting against TBI ( Traumatic Brain injury). Although there is some additional Facial coverage the test are NOT deigned or rating for protecting against Maxillofacial injuries. Let me say that I support the proposed common sense updates about “manufacture dates” whether 5 or 6 yrs. etc. But, please examine the rationale “wording”, it says or does nothing to support what appears to be an arbitrary change from FROM ALLOWING an “Approved Helmet” by the rationale’s statement itself. A very loose fitting Helmet contributes to more injuries/per accident then the differential between OPEN vs. FULL. (A long delayed haircut can cause that to happen.) Also, contributing to injuries is the fulcrum affect of upper body, clavicle injury is real, Also, Consider fatigue from Full face weight in long X-Country races( differences up to 500-850gr.).
My apologies for bad spelling on the Helmet proposal comment, thank you for your time, consideration and common sense on reconsidering this arbitrary, unsupported and unjustified wording/rule change.
After several edited versions of my original post to meet the very limited amount of spaces, my comment was not very clear on what i was trying to say. THIS COMMENT IS ONLY ABOUT “OFF ROAD” Helmets and It should be noted, approved Open Face Helmets meet the safety requirements stated in the proposal and should be allowed in Off Road events as in the past. The new updated Open Face Helmets are built to a higher safety standard then in the past and members should be able to choose their approved protective equipment for their particular event and or conditions in all OFF ROAD events. Why are so many Professional organizations like CHP, Nevada HP, Texas Troopers, Florida HP, County Sheriffs and hundreds of Police Departments still utilizing Open Face Helmets with their high speed/high risk riding? answer; SAFETY needed, SAFETY meet. Thanks again,
I think it’s been mentioned already, but what about a subclass in the LeMans race for the stock 160/175’s with rules the same as the historic production bikes?
Historic production rules would be necessary or you could still sink thousands into one of the cb160/175s. I think we other models of bike could be added as the class grows into something resembling a “super lightweight novice historic production” class LeMans start.
Current rules LeMans bikes start in the same style at the same time with the subclass bikes but are scored separately?
It seems worth a shot to see how many come out given the numbers we had in those races not that long ago and the fact it wouldn’t change our race schedule or add a class to shuffle in to race days.
Current LeMans racers can keep competing in multiple classes like they have been.
Everyone is happy?
I’m opposed to changes to the current 10.11 LeMans class machine eligibility
As stated by the committee it will eliminate current participants supporting the class. The last 2 years a Kawasaki F7 (F125) machine has won the Championship. I have participated in the class with my TA125 (F125) machine. Both of these machines cost less than the built Hondas running in the class. Allowing one brand/machine to run this class makes racers decide if they are going to spend more money buying/building a new machine to participate in the class. How many “stock” CBs are sitting around ready to come out to support the class beginning in February of 2027?
I’ve don’t believe the rules are strict enough to avoid racers still being able to build a higher performance machine based on “reliability” upgrades. Fuel requirement is still to open to many race fuels to add performance gains. A stock class should have many more limitations of modifications and fuel allowed.
I’m curious as to why the class has reduced in grid size. Could it be the cost of the race? Seems to me when the cost of the race increased; grids started to reduce (no data to support this). My suggestion would be to lower the cost of the race back down to exhibition race fee and evaluate if grids increase before making wholesale changes to the class structure.
Part 2
Racers have dedicated years/dollars developing Honda twins. It would be cost-prohibitive to modify them back to stock; they would be less competitive in 200GP. Might be cheaper to build a stocker from scratch. While the proposal does allow five-speeds, 175cc, 180mm brake, 24mm carbs, no ignition/exhaust restrictions, the ‘built’ bikes are 209cc. Many have camshaft bearing mods, racing cams, upgraded valves/cam chain tensioners, extended swingarms, frame bracing, upgraded forks/rear shocks, oil coolers, upgraded wheels/spokes/clutches. Where do you draw the line, modified and stock? Many of these mods improve durability keeping more machines on the track.
Big question: who will police stock vs. modified? While I do appreciate the rationale—cheaper, and closer racing—we are too far down the road with 200GP bike development to go this route. I believe changing the rule and adding 200GP bikes to the F125 class would boost participation; something that could be experimented with (no points for 200GP bikes) in upcoming events to see the difference in the number of entries.
Part 1
Former 200GP, Moto LeMans and F125 racer, builder. My son raced these classes and plans a future return. Racing three classes on one motorcycle made the time/expense worth it. Reducing this to one class is detrimental to those who have built competitive 200GP bikes. This boils down to $.
I reviewed four 2026 race results. Average number of entries for Moto LeMans and 200GP: eight. Six for F125. Disappointing. My 200GP race in 2015 at Barber had 48 bikes on the grid! The most important consideration for AHRMA’s survival is maximizing entry fees. Limiting a 200GP bike to one class may also make a difference in a rider’s decision to attend a race, reducing AHRMA revenue even more.
See Part 2
I give up. too many characters. I have edited my comments seven times now and it still won’t accept my very pertinent post.
I’ve already commented on my issues with this proposal, and I want to thank the board for all the work they do, and for taking the time to hear us out and read all of our comments.
I wanted to add to make clear that I believe the rule proposal as written is bad for class and org for several reasons myself and others have pointed out.
However, I believe that a more carefully considered and balanced rule change that incorporates the newer larger models is possible and would be good for the org and class. Since trustees can only vote on presented proposals the good and smart move is to decline this one, and wait for an appropriate one that is not damaging.
If this is something the actual members want, and I’m sure in the future these models will become more relevant, than I have no doubt a good proposal will be submitted by the membership that will benefit the org and racers.
I look forward to supporting proposals in the future the benefit and grow such an important class for AHRMA.
The Vintage Rules Committee approved this rule change and suggested a minimum weight. The BOT discussed that a minimum weight would be difficult to enforce yet they rejected this change because it lacks a minimum weight. In 500 Premier the B50 has no minimum weight requirement. Presently no AHRMA road racing class requires a minimum weight.
The Vintage Rules Committee commented that they wanted to avoid a “stripped down lightweight racer” but isn’t that a race bike builder’s goal?
I have no interest in being involved in racing a B50.. I do want to see more traditional styled bikes on the track.
This rule change should be approved, as recommended by the Vintage Rules Committee.
Why doesn’t Next Gen cross country have a 70+ class? The Vintage and Post Vintage MX/CC classes have one, why not be consistent?
I’ve been looking for a small-bike class that’s genuinely affordable to get into, and racing stock motors would fit that perfectly. Keeping it a rider’s race — where setup and prep matter less than raw riding skill — would be a blast, and it levels the playing field between racers with big budgets and those without.
I’d build a bike for this class if it’s adopted. It would also give riders like me another class, and another bike, to race over a weekend — which helps make the trip out worthwhile and could boost overall entries for AHRMA.
I hope the committee will consider this proposal seriously.
How about lets just focus on vintage-friendly tracks with what Jeff Smith and Dick Mann referred to as “flow” and call AHRMA our club?
With the R7/Mt07 Potentially being allowed in SOT3 but then running the 700 challenge at the same time, wouldn’t that be counterintuitive? Half of the appeal of being allowed in SOT3, is to allow racers to run in multiple classes where that bike may be competitive. Instead of being able to run 700 challenge & SOT3, we now have to pick just one. I understand the need to limit the amount of groups but if that’s the case, at least run them at separate times. I think it would benefit the organization more. Just my two pence
If the R7 is accepted into SOT3 , then 700 Challenge could be a bump class for the bike, its certainly out gunned vs an RS660 or Kramer 690
Kevin, If I am reading the 700 challange correctly, SOT3 bikes can NOT be scored in both SOT3 and the 700 challange. It will just be one race and you will have to decide in advance which class you are being scored in. You have to read the final pdf attached to the proposal.
2026.05.14-AHRMA-700-Challenge-Rule-Final.pdf.
It’s the blue hyper link at the end of the original proposal. Don’t kill the messenger. I may have misunderstood this also.
Bill, yeah, that’s a very weird way to run a race. I hope it doesn’t pass as written.
Regarding some comments of an unfair advantage of the increase to 500cc’s please see the following:
Facts- The Ninja 500 is 451cc vs 400 at 399cc
Rated HP is 51 vs 49
Rated torque is 31.7 ft lbs vs 28 ft lbs
MSRP of the 500 is $5399.00 basically unchanged from the 400
Other than a longer stroke virtually the same bike as the 400
True Supersport rules build- 54-55 HP vs 52-53 HP
Reputable builders and tuners asked agree there is no trend in 500s replacing 400s
ASRA rules opened to 500cc in 2025 and top young racers are mostly still on 400s Top 5 recently were 4 400s and 1 500
Availability of salvage Ninja 500s- shows 66 currently listed in Co-Part as they are an entry level bike subject to crashing
Putting 500s in SOT 3 creates a deficit of nearly 20 HP to a typical SOT3 SV 650 and a bump up of SOT2 which would be unsafe
Aprilia 457 or CF Moto 450 do not out perform either the 400 or 500 Ninja.
In the spirit of keeping a modern class having current models as a choice it is important to include bikes as they evolve. Regarding the Yamaha R3 and the KTM RC390, they have been out since 2008 and 2015 respectively.
I strongly disagree with this. The rule as written is terrible, and puts everyone on a 400 at a disadvantage, which is a lot of people. Why set the limit at 398 cc? Why not allow performance mods that bring power parity for ninja 400 if the intention is only to include newer models. Why not allow a +2mm piston kit and cams or some other performance indexed mods?
Even though the numbers are small, that’s still an almost 15 percent bump in peak torque for the n500, but in the midrange it’s closer to a 30 percent bump. That’s very significant at the front half of the grid! I work very hard on engines for 1 or 2 hp in sportsman 350.
Also as regards your “facts”. I believe your numbers for supersport power figures for n400 are optimistic, while for the n500 are realistic or even low. Most n400 are lucky to break 50hp and I’ve never personally seen one do it on a dyno. N500 are getting 55 with an exhaust and tune alone. Add in filters and velocity stacks and they’ll do 57 on pump gas.
As to your claim that reputable builders say there’s no trend in n500s replacing 400s, then where is the drive for this rule coming from? Who actually wants this rule that isn’t hypothetical? It sounds like a good rule to allow a couple of people to come into the class with a big power and torque advantage. I’ve seen a couple people comment in support of this rule, and they have awfully similar stances and language.
Hello Petee,
Thank you for your reply on the SOT4 proposal. I’d be happy to discuss this off line if you would like to.
My cell is 610 217 9926.
Bob
I have 2 ninja 400’s, both Superstock, both built to rule limits. One makes 46hp, the other makes 47hp. Both run at Barber on Hall’s dyno. Never seen anything legal make more. Though I’ve seen quite a few that were faster than mine.
Thank you Kevin. Our Ninja 400s which we ran four of in MA were MA Junior Cup legal with RPM restriction and intake restrictor plates making 48-49 hp on MA spec MGP fuel. 51 with those restrictions removed.
Pags Powersports built two 500s to Supersport specs with pipe, flash and filter element making 51 and 52 hp. I resting on this now but feel we have enough feedback to let the trustees make an informed decision.
One thing to always consider is a variable in dynos.
I want to talk about the real numbers currently on AHRMA’s website. If you look at AHRMA’s National Trial Site Standings you will see that there are only 2 riders in the 3 classes covering Girder, Rigid Lightweight, and Rigid Heavyweight.This is in comparison to 8 riders in just the 1 Air Cooled Mono Shock Class.Those are pretty good numbers when you consider that AHRMA excludes 90% of the Air Cooled Mono Shock Class. No one who was riding a Girder/Rigid bike back in it’s day is going to come out and ride the bike in an AHRMA Trial. Someone who has a Air Cooled Mono Shock most certainly could. At AHRMA’s Tennessee National Trial on June 7,2026 they had 17 riders. Three of those riders where riding Air Cooled Mono Shocks. That’s almost 20% of the entry competing in the trial. The word struggling was used in association with the Air Cooled Mono Shock Class. I would say it better describes the Girder/Rigid Classes. In fact the only thing the Air Cooled Mono Shock Class is struggling against is prejudice and fear of progress and growth. Finally, the Air Cooled Mono Shock is NOT a new class!! AHRMA just needs to let 100% of the Air Cooled Mono Shock Class compete. LET MY PEOPLE COMPETE!!
Addressing the committee/discussion: allowing disc brakes will open AHRMA classes to much more modern technology. It is unfortunate that so very few AHRMA members actually rode observed trials back in the day when those motorcycles were new. No one back in the day cared about what you did to your motorcycle, the technology, or the displacement of your bike.Trials is about rider skill.The only people who will benefit from disc brakes will be people riding in the Air Cooled Mono Shock class. There are members who want to see the Air Cooled Mono Shock Class allowed to compete, AHRMA has excluded 90% of these bikes because they are afraid of a disc brake.
Matt Parsons commented on how AHRMA has too many classes .Matt may have a valid point. For AHRMA trials this be could easily solved. Since AHRMA’s trials leadership is so fond of their Pre -’65 trials motorcycles we could adopt the trials class system that they use in the United Kingdom. It requires creating just 2 motorcycle classes. One class could be called the Pre-’65 True Vintage Trials Class.The other class could be called the Post ’64 Semi-Vintage Trials Class. Of course we would have 2 skill levels A and B. The section set up could be as easy as just setting up just 2 lines. Everyone would have someone in their class to compete with.Trophy presentation would be fast and easy with awards for just 4 classes.This would make life so simple.
I appreciate the opportunity to comment on the Board’s preliminary votes on Vintage Lightweight Superbike Entry ID 14335 10.8.3. I would like to respectively make the following counter points:
a) I provided detailed documentation taken directly from MotorsportReg and Speedhive supporting my proposal.
b) As I am relatively new to racing in Vintage Lightweight Superbike (VLS) I can only speak to what I have experienced during 2025. I do not see how what has happened in the past is relative to current bike advances, technology, modifications and performance.
c) I agree that rider ability certainly needs to be factored into the equation.
d) Just because a bike has always been allowed doesn’t mean that advancements in technology have not now provided that same bike with an unfair advantage. The BMW 650 is by far the speed king of the class. Turning faster lamp times than its competitors at most races.
e) I am being passed on straights by significant speed differential by the BMW. I am not experiencing that same speed differences with the other bikes in the class. My bike is a highly tuned machine.
f) I am open to and support performance indexing changes if the Board feels that is a better approach. My question is who determines if performance indexing is needed? What evidence is needed to consider the change? Does it require a wait of another year to consider?
g) Finally, even BMW considers the 650 a midsize motorcycle.
Allowing the V2 into SOT2 but not the R9 is not making sense. The bikes race together in MA, the new V2 was detuned to make the power dictated by the class, and even a Superbike spec R9 is slower than a new R6 or ZX6R which are both slower then the Krämer 890’s already in the class
The new 160 rules proposal is very much overdue. When we first started racing 160’s/175” with AHRMA, the vast majority of bikes were built to this spec, and grids were huge. As the HP wars expanded, and folks started building big ho 160/175 bikes, costs escalated out of control for engines that have an incredibly short life span. Grids shrink.
Here in the PNW we set these very simple rules over a decade ago. Everybody rides essentially the same cheap engine, making for cheap, fun, close racing. And big emphasis on cheap. With 53mm bore limit and stock cam the motors last forever. It’s very common to go more than 5 seasons with no internal maintenance. Just oil changes and fuel. Fuel? I mean pump 87 octane with a little 100 LL added for the lead lubrication and cushion for the valves. Pretty hard to beat!
Thank you all for considering this rule change. I think you are on the right track here.
Tim O
Moto Lemans is great but I can’t build a bike to just run in one class. I have a bike that is competitive in 200GP and can also race in the 250GP class as well. If I were to build a bike for the Leman class, it would be the only class where I had a chance if being competitive. It just a matter of budget for me.
I am in favor for the motor Le mans change. I had attempted to build a bike for this class and didn’t have the budget to be competitive and would be much more inclined to build a machine of this spec. Colleen Urmson #923
Moto Lemans was my introduction to vintage racing. I have 2 bikes and small stock pile of 160/175 motors just waiting for this. If it comes back to the roots of its form, I’m in!
10-11 Moto lemans. I’m for anything that creates bigger, more competitive grids. I don’t race these, but have thought about adding one as I’m sure many around the paddock have. It would definitely appeal to me more if it was more affordable. That said, if it comes to fruition l, I’d like to place an order for 2 stock class engines from Rob Hall please & thank you.
I am in favor of entry 14437 10.11 “Moto LeMans”. We have been running a similar class in the Pacific NW for many years and it’s been quite successful. The barrier to entry is low, and these motors are very reliable stock form. Here is an excerpt from the OMRRA rulebook: “-Bore size limited to 53mm. -Stock Honda 160 or 175 camshaft required. No modification of camshaft lobes.” I also recommend a cheap ($100) claim to help keep things honest. I know for a fact that many of us in the PNW would be attending more AHRMA rounds if a class like this existed at the national level.
I like the idea of including 600cc bikes in next Gen 2. Last couple races I’ve attended have only had 3-5 bikes on the grid. Would be nice to have a larger class. Although going up to ’05 may be a little late?
I think including mid-2000s 600s in nextgen3 would be good as well. For instance a friend of mine with an ’06 675 daytona was hoping to race in nextgen3 but wasnt eligible. But an 06 ducati 999 is eligible. Even a yamaha R1 of the era and alike. The 675 is already under powered. But I’d be able to race along side one of my friends and have a great time =)
For the life of me I don’t get changing one of our biggest grids by adding bigger bike and not offer the smaller ones modifications to be competitive .Nina 400’s are every place for a reasonable price and had a great class to race in .Remember the more money racers have to spend on bikes is the less they spend with ahrma. I see this as a negative impact on the club and can we handle that right now . If it a rule change that is not good for the AHRMA then it shouldn’t pass . Thanks Tim
I’m in favor of a stock lemans class. I believe it’s the perfect class to bring new racers in. When I started racing with Ahrma, it was the race that felt the least stressful, like it really was purely “just for fun.” I still love it, and it’s still my favorite class, but it feels more like a derivation of the 200gp now. I’d make a bike for the class and hopefully be able to convince friends to jump on it and come out and get their license!
I am in favor of returning the class to an exhibition class with reduced rates with less expensive bike builds. I have been racing the CB160 LeMans class since 2018 and have seen the transition from the LeMans race always being the first race for spectator consistency to random race order. There were student built bikes. There was parity in the races. Now the 160’s get left in the dust, racing against 200’s and 250’s and even formal run across the track starts are being abandoned. I believe that restoring competition to the class will encourage newer entry racers.
Would love for this to return to stock level of motor/equipment. almost a Novice Historic Production Super Light Weight where the bikes are much closer to production. This should not be limited to Hondas,
I understand the desire to create a place for newer 600cc motorcycles within AHRMA, but adding them to Next Gen Superbike 2 is not the right solution.
The class was built around a specific generation of motorcycles, and racers have invested considerable time and money developing bikes to the current rules. Later 600s may make similar or slightly less horsepower, but horsepower is only part of the equation. Their lighter weight, improved chassis, stronger brakes, better suspension, and sharper handling would likely make them the preferred platforms very quickly.
That would force current competitors either to spend heavily trying to make older motorcycles competitive with fundamentally newer designs or abandon their existing builds. In many cases, the parts needed to close that gap are expensive, difficult to find, or no longer available.
These bikes also represent a newer era than the motorcycles currently associated with Next Gen Superbike 2. Adding them would change the identity and competitive balance of an established class.
A better solution would be to create a separate class for these later-generation 600s. They are the natural next step beyond the existing Next Gen Middleweight category and deserve a class with rules designed specifically for them. That would create a place for these motorcycles to race without disrupting Next Gen Superbike 2 or devaluing the investment of its current competitors.
Maybe I am misunderstanding the rationale for rejecting the proposal to allow 3.5 inch rears in vintage road racing, so I’m making this comment. Now I have no dog in the fight but the trustee explanation saying it could cause an additional advantage for higher powered machines then in the next sentence state that current members might upgrade already legal machines for significant cost and minimal or potentially negative effect seems contradictory. Again, I might be misunderstanding, really looking for clarity here.
To open SOT4 to 500cc machines, everything 400cc and above should be performance-restricted (similar to the VSBHW framework).
My reasoning why:
• Performance Landscape Change
o A built Supersport Ninja 400 makes 52–55 hp (up from 44 hp stock).
o The US Ninja 500 starts at 51 hp stock. A Supersport build will push it past 60 hp, especially since it is heavily EPA-restricted from the factory.
o This leaves no room for the Yamaha R3, KTM 390, and Ninja 300, which make up 1/3 of our current active grid.
o Legacy bikes already struggle against the Ninja 400; they will have zero chance against an Aprilia RS 457 or Ninja 500. This 1/3 of the grid may disappear, just as the Ninja 300s and Yamaha R3 were wiped out when the Ninja 400 was introduced.
• Financial Escalation & The Aprilia Premium
o SOT4 is meant to be a budget-friendly class, but an unrestricted 500cc limit will force a costly arms race.
o The premium Aprilia RS 457 starts at a steep $6,799 retail base. Adding race parts pushes the true cost of entry past $10,000, killing the affordable nature of the class.
o SOT4 stays affordable due to “hand-me-down” race bikes coming from different AMA series. This used-bike pipeline does not exist yet for the new 500cc tier.
Thank you for your consideration
well said Jean-Marc, I agree 100%
Factually correct, and we’ll presented. Poorly crafted rule change and premature at best in it’s stated intent. Bad for the class and organization
Yes vote. I agree with Bob’s age proposal 76+ class. Please consider those riders for their safety.
I am very much in favor of the rule proposal to change the class structure for Moto Lemans (10.11). The class is not working as is with very low entries and scheduling problems. Having a class with relatively low cost basically stock bikes bikes should increase participation and provide a new point of entry for people that want to give vintage roadracing a try. The proposed class struture will also allow our roadracing friends in the west to participate in our west coast rounds with a bike they already race.
I have raced in the 160 LeMans class since 2018 and I have seen the decline in the class since 200’s and 250’s were added. Having the LeMans race be a spectator thrill at the beginning of the race day was better than being buried throughout the day. Having less expensive builds that are competitive would bring in more new racers. Remember the student builds? Encouraging more smaller bikes may create safer, more skilled, racers instead of defaulting to twist the throttle newer bikes..
I agree with Trey. I have ridden and raced since 1973 and do not like full faced helmets. especially in the woods. This should be a personal choice for the rider.
I have full face helmets for my street bike but I also have open face for the street. Thhis change is out of line for AHRMA.
Please reconsider allowing the Master Level to be used by the Premier trials riders if they choose to. This affords the Premier class riders an option should they desire an additional challenge. Thank you.
Sean, I believe if a rider wants to ride a more difficult line he is free to do that.
If it’s not enough challenge for you, you can ride a more difficult line on a premier bike since there’s nothing stopping you from riding the newer class on an older bike.
I also meant to say there are way too many classes across all disciplines in AHRMA.
How much fun is it to go out and compete against maybe one other person in some of the classes?
It also makes the day longer and more difficult for the promoters, etc.
I still wish people could realize the trophy is riding our old bikes on appropriate courses with our buddies.
Not have the focus on a cheap trophy and a round of applause for beating no one.
Every effort should be made to keep riders in the organization. Previous attempts to make an 80+ class were rejected and now 76+ also seems likely to fail as well. Suggestions to add youth classes were likewise struck down. If we continue doing the same thing year after year I am afraid our numbers will continue to dwindle… Let’s give our older riders some incentive to keep coming to the races.
We all grew up with open face helmets in the 60s and 70s. I think it should be rider discretion. I would hate for some new rule change to eliminate me from riding your events. I’ve been a member since 2007. No more open face mx. No more participation on my part.
After reading the current proposal to ban open face helmets to all off road competition except trials, I must voice my opinion. As an AHRMA member in good standing since 1999 I have competed in VMX competition using an approved open face helmet and I have never questioned my safety while wearing this type of helmet. I have always inspected my helmets and replaced them when damaged or 5-6 years of use. I have never experienced any facial injuries in the last 27 years of competition using open face helmets. I’m wondering what “risk” it is to the AHRMA organization by competing while wearing an open face helmet. Don’t we all sign a release of all liability at every competition event? If this is true, what “reduction of risk “ is there by banning approved open face helmets? I’m sorry to say, if open face helmets are banned, then my days of VMX competition with AHRMA will be over.
Allowing those more modern 600’s into Next Gen 2 would ruin that class. The 600’s do make less HP, but power to weight ratio’s and their scalpel like handling would see them rise to the top quickly. The cost to make the existing legal bikes competitive with more modern 600′ s would be exorbitant, that is, if you could get the parts. The more modern 600’s goes against the mission of the Next Gen classes of recreating and preserving the look and feel of the U.S. Superbike racing. I think a good concession to this rule proposal would be to allow the 1999-2001 Yamaha R6 into the class for next year and see how it goes. That specific year R6 is carbureted, makes decent power, but has exceptional handling. It would be a good barometer and first step for future requests. Jumping right in with 2005 R6’s and 2004 GSXR600’s has the potential to disrupt the whole class and turning it into a modern 600 class.
I did like John Turner’s idea of putting these more modern 600’s in the SOT2 class. Competing with Triumph 765, Kramer’s and other more modern bikes.
I’m 100% against this proposal. Its allowing 500’s into the class and holding the currently legal Ninja 400 to same superstock specs as it has today. Purposely selecting 398ccc as the maximum when the Ninja 400 is 399cc stock. You’ll allow bigger, newer , faster bikes into the class and not allow the Ninja 400 to be updated to compete. We’ll all be buying new bikes if we want to stay competitive, or we just stay home. This is a poorly thought out proposal that will destroy the class. I urge my trustees to take a long look at this one.
adding to my comment, there is already a place for 500cc twins to race, its SOT3. Why do we need to change the rules for SOT4 when those proposed bikes are already welcomed in SOT3?
I am in agreement with the boards preliminary decision to allow SOT4 twin-cylinder machines up to 500cc of displacement in supersport spec. Our Modern roadracing classes need to change with the current models produced so these bike have a competitive class to enter. SOT3 is too big a leap for the 500cc machines to make.
I ran my 400 in SOT3 for two years before SOT4 included them. Lets see some 500’s show up to race before we make rule changes. They fit in SOT3 today.
I agree. Where are these 500s? I believe this rule change is at best premature. It is poorly crafted and will harm the class and the organization in its current form.
Section Number 3.3.14. I dissent on the requirement for motocross helemets to be full face. I aknowedge that such helemets are safer than open face helmets, but we are grown ups and can make our own decision about the level of risk we are willing to take. In fact the rationale for the rule change is pure CYA – it is to protect the organization, not the rider. But we already sign away our rights to sue, barring negligence, and adding this rule isn’t going to change anything regarding liability. Indeed, why stop with helmets? Why not require full leathers, armor, kevlar chest protectors, and training wheels? Somehow we survived the racing in the Olden Times without full face helments. Please, enough with the Nanny State.
