AHRMA also offers modern roadracing classes. Click here for details.
VINTAGE ROADRACING MISSION STATEMENT: AHRMA’s mission is to recreate and preserve the vintage era of roadracing, including the sights, sounds, smells and camaraderie. Many consider the 50-year time span – from the 1930s to the mid-‘70s – the golden age of roadracing. We recognize that the oldest of these motorcycles are the least available; therefore only small numbers are likely to participate in most events, and some events may have no examples. However, AHRMA is committed to maintaining a venue to showcase these early motorcycles, no matter how few.
VINTAGE SUPERBIKE MISSION STATEMENT: AHRMA’s mission is to recreate and preserve the look and feel of this important era of U.S. Roadracing and to showcase these unique machines. While Superbikes were based on the same production bikes available in the showroom, period performance parts are extremely rare or even unavailable; therefore, a limited amount of modern replacement parts are allowed in the interest of safety, cost containment and competition.
