Post Vintage Motocross
MISSION STATEMENT: The mission of AHRMA Post-Vintage Motocross is to showcase an innovative and revolutionary period of MX racing. This relatively short time-frame is recognized as the beginning of the long-suspension-travel era of motocross which lasts to this day, and also the emergence of the American domination on the world racing scene. Machines of this era were purpose-built motocross racers which introduced many technologies, from the very first long-travel suspension through to the advent of water-cooled engines and
linkage-controlled rear suspensions found at the end of this exciting time in motocross.
These technological advances result in a motorcycle which has the ability to travel at incredible speeds over very rough terrain, and endure punishment that would have inflicted race-ending damage to earlier machines. These capabilities, coupled with advancing riding styles and techniques, dictated changes in the racetracks. Tracks became specially prepared, permanent-style circuits, which utilized some man-made obstacles in addition to natural terrain features. The Post-Vintage era ends as we start to see the inclusion of Supercross-style obstacles in the tracks, and the inclusion of disc brakes and other advanced features from the factories as original equipment.
The primary purpose of AHRMA Post-Vintage Motocross is to provide an appropriate place for these machines to be preserved and ridden by those who are interested in reliving the era, in addition to educating and exposing the history to those who may not have been participants the first time around. With careful attention to race track preparation, and to rules crafting, AHRMA is making certain that Post-Vintage Motocross bikes will be enjoyed by its members of today and tomorrow.
