The American Historic Racing Motorcycle Association Ltd. is a not-for-profit organization dedicated to restoring and competing on classic motorcycles. AHRMA has over 5,000 members and is the largest vintage-racing group in North America and one of the biggest in the world. The association has grown steadily over the years, reflecting the increasing interest in classic bikes.
AHRMA traces its roots to efforts to organize vintage roadracing during the late 1970s in the Northeast. In the early '80s, other groups began emerging around the nation, adding scrambles, observed trials, dirt track and concours events to the competition options available for vintage riders. Among these organizations were the California Vintage Racing Group and, in the Southeast, the Historic Motorcycle Racing Association. By 1986 it was clear that a national organization would be necessary to administer this burgeoning sport. AHRMA was originally formed as a privately held business corporation. Other groups were brought together under one banner and one set of rules, and in 1989 AHRMA was reorganized into the member-owned association of today.
AHRMA offers national and regional Roadracing, Motocross, Flat Track, observed Trials and Enduro or cross country competition for vintage motorcycles. The machines active in AHRMA these events span a full 50 years, from the 1920s to the mid-'70s. The national-championship schedule typical includes 15-20 rounds apiece in roadracing, motocross, dirt track, cross country and trials. AHRMA nationals take place at some of the finest and most historic venues: Daytona, Mid-Ohio, Sears Point, Willow Springs and Peoria, to name but a few.
Realizing that the definition of "classic" varies from one generation of enthusiasts to the next, AHRMA has in the past few years begun to add classes for long-travel motocross machines from the late 1970s to early '80s and for roadracers from early in the AMA Superbike period (up to the 1980 model year). These Post-Vintage motocross classes have been incorporated in many of AHRMA's regional series and also have their own national circuit. The three Vintage Superbike classes have been added to AHRMA's normal roadrace program.
