From the December issue of Vintage Views
2003 rule-change summary

Note: The 2003 AHRMA Handbook is being mailed with the December Vintage Views. The on-line version will be posted no later than the first week in December.

The Board of Trustees met Nov. 9 and 10 in Oakland, Calif., to make final decisions on rules proposals discussed at their September meeting in Colorado. New language in the 2003 AHRMA Handbook is underlined, so it is fairly easy to spot. Wording that has been removed, however, is a little more difficult to recognize—it’s simply gone!

To make it easier to track the changes, we offer the following summary of what’s new in the 2003 rulebook. The October VV contained a report on the board’s preliminary action on most of the rules proposals.

If you have questions, please contact the appropriate rules and eligibility committee. All contact information for committees and other AHRMA officials can be found in Section 17 of the book.

Roadracing

The question of allowing the Gardner carburetor in 350 Grand Prix was revisited and defeated again.

Clarification was included that Can-Am 250s in Formula 250 may have aluminum or magnesium cases but are limited to engines with 57.5mm stroke. A request was made to allow later long-stroke engines, but trustees concluded that these are beyond the cutoff date and not of like design.

Based on member input, trustees reversed an earlier decision that would have allowed the Triumph T100 twin roller bearing engine in Classic Sixties. Instead, the class structure remains unchanged. Weslake (Nourish) pre-unit engines will be permitted in 500 Premier.

In Historic Production, the Honda CB400 four-cylinder was moved to the Lightweight class. The carburetor rule was revised to specify that replacement units must be OEM and of the same type they are replacing (for example, CV carbs must be replaced with CVs).

In Vintage Superbike, the board approved the proposal to allow pre-1980 1025cc four-cylinder AMA Superbikes, limited to 29mm carbs and meeting all chassis rules. The Vintage Superbike classes also will allow forks up to 41mm in diameter, and permit approved period aftermarket swingarms and accurate replicas. Allowable rim width was increased to 4.5 inches. The restriction in the Heavyweight class limiting Kawasaki 900s to the Z-1 with no updates was eliminated.

Battle of Twins classes were revamped as follows: F-3—pushrod OHV machines to 900cc, OHC two- or three-valve to 750cc, OHC liquid-cooled four-valve to 650cc. SV650 Suzukis in F-3 are now limited to SuperStock specifications. F-2—pushrod OHV machines to 1250cc, liquid-cooled OHC to 750cc and air-cooled two-valve OHC to 1000cc. F-1—no displacement limits and no limitations to engine modifications, with the exception that water-cooled four-valve twins over 900cc must conform to SuperStock specs. BOT Two-Stroke—air-cooled two-stroke motorcycles to 500cc; water-cooled two-strokes with tubular frame to 400cc; water-cooled parallel twins with "Delta Box" style frame to 250cc; and 250cc V-twins limited to SuperStock specifications.

Because a concrete proposal was not forthcoming for creating a class similar to the International Classic Grand Prix Two-Stroke run at Daytona, the request was tabled until the 2004 rulebook. However, the class will again be offered at DeLand and Daytona in 2003. The board voted to reaffirm an earlier decision to drop the Cosmo Cup class after the 2002 season.

In Production Singles, the requirement that machines originally be sold as street-legal models was removed to open the class to supermotard-type motorcycles. Maximum brake diameter was set at 320mm for machines in this class. Even though the rules don’t specifically say so, this is a four-stroke-only class.

Among the general rules, faceshield tear-offs now are prohibited in roadracing. Also, the rule regarding red flag restarts was modified as follows: "In races of six laps or fewer, if the red flag is displayed before two laps have been completed, the race will be restarted from the original grid. If the red flag is displayed after two laps but fewer than four, the restart will be from the riders’ positions on the track. If more than four laps have been completed, the race will be considered complete. In races of more than six laps, if fewer than half the laps have been completed with the red flag is thrown, the race will be restarted from the original grid. If more than half the laps have been completed, the race will be considered complete."

Dirt track

Two changes are simply clarifications of existing rules—one that only 250cc Harley-Davidson/Aermacchi machines, not 350s, are legal in Classic 250, and the other that all machines in TT classes, including Seventies Singles, must conform to the 7-inch/4-inch maximum suspension travel limits. Additionally, it was emphasized that only Can-Am 250cc engines with 57.5mm stroke are legal.

The 30mm carburetor limit for Bultacos in Classic 250 was changed to the same 32mm limit as other two-strokes in the class.

Sportsman chassis wording in rule 15.5d was replaced with the following: "Sportsman class machines may use a production chassis from 1974 or earlier, or an aftermarket chassis of the type and configuration used in North American dirt track competition prior to 1975. Typical eligible models include Champion, Trackmaster and Redline. Others must be submitted to the Dirt Track Rules & Eligibility Committee for an eligibility decision. Requests must be accompanied by documentation and photographs establishing the configuration and appropriate time-line. Accurate replicas of eligible dirt track aftermarket chassis are eligible as long as they conform to the original design and other class rules."

Veteran will be eliminated as a national-championship class after 2003 (but still may be run as a support class). The Dirt Track Rules & Eligibility Committee wants suggestions for a replacement that can be presented at the Florida board meeting in March. Under consideration so far are Seventies Two-Stroke, Seventies Twins or a brakeless class for riders over age 50.

Motocross

Trustees initially voted to create a Premier Open class for 600cc singles and 650cc twins, but later rescinded that action and instead will instead seek member input on how to best accommodate the 600s. Also in the Premier classes, the following was added at the end of the Premier portion of rule 11.2b: "Premier Lightweight four-strokes must utilize the original cylinder-head castings. Villiers Starmaker-powered machines are limited to the early "MkI" style, coarse-finned cylinder. Villiers 32A-37A-powered machines may use any period aftermarket alloy cylinder, the Greeves Challenger head/cylinder and/or Alpha- manufactured crankcases."

In the Classic classes, Rickman-Montesa four-speeds were made eligible for Classic 250 with certain restrictions to keep them as near original as possible. In response to concerns of a Classic 125 "arms race," carburetor size was limited to 32mm and exhaust pipe construction specified as: "Any OEM exhaust may be used only on original bike; any replacement of original exhaust must be made of up to four rolled cones and a single diameter center section and a single diameter head pipe."

For the Sportsman classes, a note was added for Can-Am 250s specifying that only engines with 57.5mm stroke are legal. At the request of AHRMA’s national tech inspectors, all requirements that like-design 1975-model machines use 1974-configuration swingarms were changed to "1974 swingarm configuration encouraged."

A +70 class was created, and trustees reaffirmed that riders over age 70 do not pay an entry fee.

In the post-vintage classes, most of the changes dealt with eligibility clarifications. These included wording identifying the Husqvarna 390s eligible for Historic 500, 360 Mugen-kitted Honda CR250s in Gran Prix 500, TT500 Yamahas through 1980 in Historic Four-Stroke and Historic 500 (provided they meet the suspension limit), and Ossas with Bolger suspension in Historic 250.

A revised post-vintage carburetor rule was approved as follows: "Period-type carburetors are strongly encouraged. Period flat-slide carbs are allowed on Historic and Gran Prix class motorcycles. Examples include Lake, Lectron, Poso and other period-type flat slides. Active accelerator pump equipped carburetors are allowed only on Ultima class motorcycles or if OEM equipped for that particular motorcycle. 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 flat slide Mikuni and Keihin carburetors are allowed only on Ultima class motorcycles. No modern D-shape slide or similar equivalent carburetors are allowed in AHRMA Post-Vintage off-road competition."

As a test to see if these additional post-vintage classes could be viable, AHRMA will allow a Gran Prix Four-Stroke and Ultima Four-Stroke class to be utilized by regional coordinators if they so choose. The class structures are outlined in the rulebook.

Duplicate vintage and post-vintage rules were consolidated in the vintage section, with appropriate references in the post-vintage rules. This section contains slight revisions to rules governing passing under a yellow flag, instances where riders may hold dual ability levels, the "last-place-plus-two" scoring rule and the number of events that count toward series awards. The penalty for jumping the start was changed from one lap to the loss of three finishing positions. Paddle-type tires are now prohibited.

Observed trials

Trials riders will want to study their section of the rules, because there are extensive additions that deal with how events are organized and run. The Trials Rules & Eligibility Committee based the changes on an 18-page proposal submitted by Len Sims.

The board turned down a proposal to allow aftermarket reed valves on two-stroke machines in the Classic class. As a result, these items remain illegal.

Cross country

Several motorcycles were included as examples of eligible machines for the 0-200cc cross country class—Bultaco 175/200, Husqvarna 175, Penton/KTM 175 and Puch 175. The Honda MR175 was specified as a Post-Vintage class machine.

A reference to motocross rule 11.4c—defining non-starter, non-finisher and finisher—was added.

General rules

All references to the number of intake/exhaust valves in an engine now are valves per cylinder. This is explained in the Definitions section at the front of the book.

Following an incident with a quick-release fastener at a roadrace late in the season, only OEM chin straps fasteners will be permitted on helmets (rule 3.3.14). The board accepted the British BSI 6658 Type A ("blue label") helmet standard along with the Snell 95 standard in roadracing and dirt track (3.3.14).

Corrections

Below are the first corrections to the 2003 AHRMA Handbook. Please make note of them in your copy.

From the October issue of Vintage Views
Board action on 2003 rules proposals

The Board of Trustees met Sept. 13 in Denver, Colo., to consider rule changes for the 2003 AHRMA Handbook. What follows is a look at board decisions on a wide array of proposals on a discipline-by-discipline basis. All votes on the proposals were tentative. Trustees will meet again on Nov. 9-10 to finalize next year’s rules. If you want to offer an opinion on any of the proposals, please do so in writing (mail, fax or e-mail) as soon as possible to the national office, or contact any of the individual trustees (click here for contact information). The final rule decisions will be summarized in the December VV. Your 2003 handbook also will be included with that issue.

Roadracing
• Increase overbore limits to prolong the usable life of cylinders. Vote: No. AHRMA already has liberal bore limits, and the proposal would have the potential to create a new horsepower war.
• Allow early win-shock TZs in the Formula 250 and 500 classes. Vote: No. The classes are fine as is.
• Allow four-cylinder machines in all Formula classes to use Keihin CR-type carburetors. Vote: No.
• Clarify that Can-Ams in Formula 250 may have aluminum or magnesium cases but are limited to engines with 57.5mm stroke. Vote: Yes.
• Allow the Triumph T100 twin roller bearing engine in Classic Sixties. Vote: Yes.
• Allow Weslake (Nourish) pre-unit engines in 500 Premier. Vote: Yes.
• Permit Hondas up to 200cc in 200 GP and remove 250cc machines from the class. Vote: No. The class is fine as is.
• Allow the Gardner carburetor in 350 GP. Vote: No (two dissenting). The committee had recommended the change, reasoning that experience in 500 Premier shows that the Gardner is less expensive than an Amal GP, easy to tune and has no apparent performance advantage.
• Eliminate “period style replacement” from Historic Production carburetor rule 10.6.4a and revise to specify that carburetors “must be OEM, same type (e.g., replace CV with CV).” Vote: Yes. The change is intended to ensure the class remains entry- level.
• Move the Honda CB400 four-cylinder from Historic Production Heavyweight to Lightweight. Vote: Yes.
• Place the Honda CB400 in Vintage Superbike Middleweight (committee recommendation). Vote: Leave it in Lightweight (one dissenting).
• Eliminate the restriction in Vintage Superbike Heavyweight that limits Kawasaki 900s to the Z-1 with no updates. Vote: Yes.
• Increase the allowable rim width to 4.5 inches in Vintage Superbike. Vote: Yes. Opens up more tire choices without necessarily increasing speeds.
• Allow forks up to 41mm diameter in Vintage Superbike. Vote: Yes.
• Allow pre-1980 AMA four-cylinder, two-valve Superbikes from the period, limited to 29mm carbs and meeting all chassis rules. Vote: Yes.
• Divide BOT Two-Stroke into three subclasses. Vote: No.
• Open BOT Two-Stroke to 250cc V-twins limited to SuperStock specifications. Vote: Yes. The change would allow Aprilia Cup type machines in the class.
• Create a class analogous to the International Classic Grand Prix Two-Stroke race run at Daytona. Tabled until November meeting.
• Restructure the BOT classes as follows: F-3—pushrod OHV twins to 900cc; OHC two- or three-valve twins to 750cc; and OHC liquid-cooled four-valve twins to 650cc. F-2—pushrod OHV twins to 1250cc, liquid-cooled OHC twins to 750cc (the Ducati 748 water-cooled four-valve must run in F-1); or air-cooled two-valve OHC twins to 1000cc. F-1 remains the same, except that liquid-cooled four-valve twins over 900cc (rather than 800cc) would be limited to SuperStock specifications. Vote: Yes.
• Remove the phrase “intended for street use only” in Production Singles to open the class to supermotard-type machines. Vote: Yes.
• Modify the rule regarding red-flag restarts for races of various lengths. Vote: Yes.
Note that the rulebook will be clarified so that all references valves in BOT and SOS classes will mean the number of valves per cylinder.

Dirt track
All of the following proposals were recommended by the Dirt Track Rules & Eligibility Committee and tentatively okayed by the board.
• Clarify that Aermacchi/H-D Sprint machines in Classic 250 must be 250cc, to avoid confusion with illegal 350cc models.
• Eliminate the 30mm carburetor restriction for Bultacos in Classic 250 and impose the same 32mm restriction that applies to other two-strokes in the class.
• Eliminate Veteran as a national-championship class after 2003 and replace it with another class to be determined. Promoters could run Veteran as a support class after 2003.
• Replace the current Sportsman chassis wording in rule 15.5d with the following: “Sportsman class machines may use a production chassis from 1974 or earlier, or an aftermarket chassis of the type and configuration used in North American dirt track competition prior to 1975. Typical eligible models include Champion, Trackmaster and Redline. Others must be submitted to the Dirt Track Rules & Eligibility Committee for an eligibility decision. Requests must be accompanied by documentation and photographs establishing the configuration and appropriate time-line. Accurate replicas of eligible dirt track aftermarket chassis are eligible as long as they conform to the original design and other class rules.”
• Emphasize in the TT rules (14.5d) that Seventies Singles machines must conform to the same 7-inch/4-inch suspension travel limits as other classes.
Suggestions are being solicited for a replacement class for Veteran. Among those posed so far are a Senior class for brakeless machines, a split of Senior into heavyweight and lightweight divisions, and a Seventies Two-Stroke or Seventies Twins class.
The board discussed but took no action regarding concerns about the dominance of Sportsman 250 by Can-Am-powered machines. It was noted that only Can-Am engines with a 57.5mm stroke are vintage-legal.

Vintage motocross
The following proposals were granted tentative approval:
• Remove “also TS models” from the list of Suzuki models in Sportsman 125. These machines are already listed as eligible for Classic 125.
• At the end of the Premier paragraph in rule 11.2b, add: “Premier Lightweight four-strokes must utilize the original cylinder-head castings. Villiers Starmaker-powered machines are limited to the early “MkI” style, coarse-finned cylinder. Villiers 32A-37A-powered machines may use any period aftermarket alloy cylinder, the Greeves Challenger head/cylinder and/or Alpha- manufactured crankcases.”
• Change the opening sentence of 11.3e to: “If the rider grading committee deems it appropriate, riders in the +50 and +60 classes may have a dual ability level, with a lower rating in the Sportsman classes only.”
• Change 11.6f to: “A yellow flag indicates a dangerous situation on the track ahead. A rider may pass another competitor in the yellow-flag area if it is safe to do so, but extreme caution is necessary.”
• Add a note in Sportsman 250 pointing for Can-Ams pointing out that only engines with 57.5mm stroke are legal.
• Create a Premier 600 class for the James Holland Matchless 600 and other 600cc machines eligible for Premier 500. The class is to be run along with Premier Open Twins and will allow Premier 500 machines to bump up.
The R&E committee is still considering a request to allow the four-speed Rickman Montesa 250 in Classic 250. The committee also wants input on proposing carburetor (suggested 32mm) and exhaust restrictions for two-strokes in Classic 125. Some machines in the class are displaying unusually high performance.
The committee did not recommend approval these proposals: reduce the penalty for jumping the start; allow five-speed Maicos in the Sportsman classes; allow the 1968-69 Maico X4 machines in the Classic classes; allow the Suzuki RM125 in Sportsman 125; reduce the Classic 125 displacement limit for four-strokes to 125cc; distribute championship points in the event of a complete rain-out; allow 100cc machines in Classic 125 to add reed valves; and drop all requirements of 1975-model machines to use ‘74-spec swingarms.
Trustees spent considerable time discussing proposals to add youth classes and reiterated the board’s opposition to such a concept.
A proposal was made to increase the displacement limit for four-strokes in Sportsman 250 to 312cc to allow the use of a Powroll big-bore kit. However, it was determined that the kit is currently legal at 297cc when the 0.080-inch overbore is subtracted.

Post-vintage MX
The board agreed with several rules changes, corrections and clarifications offered by the Post- Vintage MX Rules & Eligibility Committee:
• No paddle-type tires are allowed in any AHRMA post-vintage off-road competition.
• Make the air-cooled 360 Mugen-kitted CR250 Hondas from 1978-up legal for the Gran Prix 500 class. This is a clarification of what the committee always intended.
• Keep the 1978 Suzuki RM125 classified as a Gran Prix 125 motorcycle.
• Add the following carburetor rule: “Period-type carburetors are strongly encouraged. Period flat-slide carbs are allowed on Historic and Gran Prix class motorcycles. Examples include Lake, Lectron, Poso and other period-type flat slides. Active accelerator pump equipped carburetors are allowed only on Ultima class motorcycles or if OEM equipped for that particular motorcycle. Dell’Orto accelerator pump carburetors are allowed in the Gran Prix classes only if the accelerator pump mechanism is disconnected or removed. Period flat slide Mikuni and Keihin carburetors are allowed only on Ultima class motorcycles. No modern D-shape slide or similar equivalent carburetors are allowed in AHRMA Post-Vintage off-road competition.”
• Allow TT500 Yamahas up to 1980 to run in the Historic Four-Stroke class, provided they meet the 9-inch suspension travel limit.
• Remove the incorrect reference to a +60 class on page 82 of the handbook.
As a test to see if these additional post-vintage classes could be viable, AHRMA will allow a Gran Prix Four-Stroke and Ultima Four-Stroke class to be utilized by regional coordinators if they so choose. Gran Prix Four-Stroke will follow the same guidelines as the Gran Prix class formula, with no suspension travel limitations. Upside-down forks are not allowed. The Ultima Four-Stroke class can include: Can-Am Sonic; Husqvarna 510 TC, TX TE; 1981-82 Honda XR 500; and C&J single-shock frame bikes with Rotax, Yamaha or Honda engines. Upside-down Simons and early White Power forks are allowed on Ultima class motorcycles only.

Trials
Proposals will be presented to the board at the November meeting, including one which comprehensively outlines how events are to be conducted.

Cross country
Several motorcycles will be added to the Sportsman 250 motocross class lists of eligible motorcycles as reference points for the 0-200cc cross country class. These include Bultaco 175/200, Husqvarna 175, Penton/KTM 175 and Puch 175. The Honda MR175, it was emphasized, is a Post-Vintage class machine and will be included in the list of Historic 250 motorcycles.
A reference to motocross rule 11.4c—defining non-starter, non-finisher and finisher—will be added as rule 15.1.2c.

From the September issue of Vintage Views
2003 member-submitted rules proposals

Member proposals for 2003 rules changes have been distributed to the various rules & eligibility committees, and now is the time for any interested AHRMA members to offer their views on these suggestions. At the Board of Trustees meeting on Sept. 13, the committees will make their recommendations to the board. The trustees will give tentative approval or disapproval to the changes presented by the committees. A summary of this action will be published in the October Vintage Views, and members will again have the opportunity to comment before the board meets in late October or early November to finalize the 2003 rulebook.

The proposals are briefly summarized below. If you would like to offer an opinion on the proposals, please send your comments as soon as possible to the appropriate rules & eligibility committee. Contact information can be found on pages 108-109 of the 2002 AHRMA Handbook, or on the website at www.ahrma.org/rulebook/sec17.html.

Vintage roadracing
• Allow four-cylinder machines in all Formula classes to use Keihin CR-type carburetors. Currently these are permitted only in F-750.
• Change bore limits to .100 inch for singles, .080 for twins, .060 for triples and .040 for fours. This would allow competitors to extend the useable life of cylinders with one more bore without giving a large advantage in performance.
• Allow the Gardner carburetor to be used in 350 GP, as it is in 500 Premier.
• Add early (twin-shock) Yamaha TZ250s to Formula 250 and TZ350s to F-500. The machines have little or no performance advantage over their air-cooled brethren.
• Allow the Honda CB160 and 175 to run at the 200 GP class limit of 200cc plus allowable overbore, and remove 250cc machines from the class.
• Move the Honda 400-4 from Vintage Superbike Middleweight to Lightweight.
• Allow Weslake (Nourish) pre-unit engines in 500 Premier, and make the Weslake (Nourish) four-valve head ineligible (it was listed as eligible on a probationary basis for 2002).
SOS/BOT/SOT roadracing
• Due to the dominance of the Suzuki SV650 in Battle of Twins Formula 3 class and ability of these machines to also win F-2, the classes should be restructured so that F-3 is limited to two-valve machines up to 650cc and multi-valve engines to 550cc; F-2 would be open to two-valve engines to 800cc, three-valve engines to 700cc and four-valve engines to 650cc.
• Change BOT F-3 to air-cooled twins to 750cc, 8-valve water-cooled engines to 650cc, water-cooled twins with fewer than 8 valves to 700cc; F-2 would add air-cooled OHC twins to 1000cc; and F-1 would impose SuperStock specifications only on 8- valve twins over 900cc. The changes would make air-cooled Ducatis, the Ducati 748 and Honda Hawk more competitive, and make F-2 “something other than a rehash of F-3.”
• Split BOT Two-Stroke into three subclasses—up to Dec. 31, 1990, Deltabox 250s, with 17-inch wheels; up to Dec. 31, 1984 250s with steel frames and 18-inch wheels; and up to Dec. 31, 1980, 250s with steel frames and 18-inch wheels.

General roadracing
• The rule regarding red flag restarts should be modified as follows: In races of six laps or fewer, if the red flag is displayed before two laps have been completed, the race will be restarted from the original grid. If the red flag is displayed after two laps but fewer than four, the restart will be from the riders’ positions on the track. If more than four laps have been completed, the race will be considered complete. In races of more than six laps, if fewer than half the laps have been completed with the red flag is thrown, the race will be restarted from the original grid. If more than half the laps have been completed, the race will be considered complete.

Vintage motocross
• To better reward moto winners in calculating overall class wins, a moto win would receive zero points, second place 1 points, etc. In the event of a tie at day’s end, the tiebreaker would go to the person with the moto win.
• Limit the Honda 125 four-stroke to 125cc in Classic 125, and move the 150cc version to Sportsman 125.
• Allow the 1975 Suzuki RM125M engine to be used Sportsman 125 if fitted in a Sportsman-eligible frame. The engine shares many of the changes made to the ‘75 TM125, which is currently eligible.
• Make the 1975-75 Maico five-speed engine eligible for vintage competition. It is identical to the pre-1975 engine except for the transmission.
• Change the limit for four-strokes in Sportsman 250 from 300cc to 315cc, which would open the class to Honda XL250s equipped with the popular Powroll big-bore kit. Currently, such machines are not competitive in Sportsman 500.
• Allow 100cc motorcycles that did not come from the factory equipped with a reed valve to compete in Classic 125 with a reed valve.

Post-vintage MX
• Include the 1978 Suzuki RM125 in the Historic 125 class. The only changes to the ‘78 model were a plastic gas tank and an aluminum swingarm, and aftermarket aluminum swingarms are allowed in the Historic class.

General motocross
• If an event is canceled because of weather or other reasons on the day of the event before any motos have run, riders who have registered and gone through tech inspection would receive points as if the motos had run and they finished in the last position in their class. If there are 15 or more riders in a class, each would receive 2 series points.
• Add the following youth classes to encourage more family participation: 60cc, through age 8 on any motorcycle up to 60cc; XR75, through age 14 on any AHRMA-legal twin-shock Honda XR75/80; Vintage 80cc Beginner, ages 9-12; Vintage 80cc Advanced, ages 12-14; Vintage 125cc Schoolboy, ages 12-16; Post-Vintage 80cc Beginner, ages 9-12; Post-Vintage 80cc Advanced, ages 12-14; and Post-Vintage 125cc Schoolboy, ages 12-16.
• Reduce the penalty for jumping a start to loss of one or two positions, or use the stop-and-go “meatball” flag as in roadracing. The current one-lap penalty is too harsh.
• Revise the wording regarding dual ability levels for +50 and +60 riders to make it clearer that a rider can be assigned lower ability rating for the Sportsman classes only with the approval of the rider grading committee.

Dirt track
• Divide the Senior class into Lightweight (0-500cc) and Heavyweight (501-750cc).
• Remove or increase the maximum carburetor size for two-strokes in Classic 250 to restore competitiveness.

Trials
• Extend eligibility to include trials bikes from the early-to-mid 1980s with drum brakes and air-cooled engines, as has occurred in AHRMA motocross and roadracing.
Also submitted was an 18-page proposal detailing extensive changes to the trials rules section, aimed at providing a uniform set of guidelines for conducting an event. The proposal sets standards for the course (loop and individual sections), scoring procedures, penalties, time limits, scorecards, tiebreakers, protests and much more.

Cross country
No proposals offered.
