Vintage Motocross Mission Statement

The mission of AHRMA Vintage Motocross is to preserve a particular time in the history of the sport of motocross. This time period may not be the very beginning of the sport, but marks the period of international recognition after WWII. It ended in the mid-1970s, and is considered to many around the world as one of the greatest eras of the sport. We want to show why this is said.

At the beginning of this time period, the machines raced were basic transportation-based models with slight modifications. They were raced over farmland settings with natural challenges. Higher speeds, terrain and off-camber turns provided the main challenges on these tracks that are typical of those used into the early ‘70s. Our era ends with the advent of specially designed racing machines on specially prepared tracks. The main things consistent during this time period were the amount of suspension travel and the technique used to race these machines on natural tracks.

AHRMA Vintage Motocross is dedicated to preserving these machines, the sights and sounds, the racetracks and the riding techniques and strategies of this bygone era. Our rules are carefully crafted to make sure these machines will never become obsolete again.

Refunds will be issued only to pre-entered riders who have filed a Refund/Credit Request Form with the AHRMA National office. A refund form is in the Handbook, may be obtained from the office, or can be downloaded here. The form may be filed by mail, email, fax, or the office may be telephoned with the relevant information. Please see AHRMA Handbook rule 4.7 for more details.
