Dirt Track Mission Statement

Dirt track racing has been the mainstay of American motorcycling since the earliest days and blossomed into a unique American sport with the advent of Class C racing by the AMA in the 1930s. The proliferation of dirt ovals throughout America led to further development of this 100% American sport up through the 1970s, resulting in several distinctly different forms of racing motorcycles — each developed to suit the rules of the time period and optimized for dirt oval racing.

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.
