The American Historic Racing Motorcycle Association has attempted to preserve the sights and sounds of this uniquely American sport and display it to the public by providing a set of governing rules intended to capture each distinct period of dirt track racing (Class C, brakeless, vintage, and Seventies era) and pit the motorcycles of that period against each other in fair competition. Races are held on a variety of dirt tracks, ranging from short tracks, half-miles, miles and Tourist Trophy circuits, with National points awarded to encourage participation and recognize achievement. The rules are written to provide safe and suitable competition classes for as many period motorcycles as possible while maintaining level competition between different types and preserving the historical basis for each class. A concerted effort is made to maintain a stable rules structure so that members may participate with their machines for an extended period of time without having to upgrade or modify their motorcycles to adapt to changing rules.
