The AMA Supermoto Championship was an AMA Pro Racing-sanctioned Supermoto motorcycle racing series that ran from 2003 through 2009. AMA Pro Racing was a wholly owned subsidiary of the American Motorcyclist Association. An amateur national championship, known as AMA Supermoto and sanctioned by the American Motorcyclist Association as AMA Sports, was launched in 2013 with USA Supermoto as the new promoter.
Main classes consisted of Supermoto (also later known as Supermoto Premier) for 400-450cc, four-stroke, single-cylinder motorcycles, and Supermoto Unlimited, open to two-stroke, single-cylinder motorcycles 490cc and greater, four-stroke, single-cylinder motorcycles. Support classes included the Honda Junior Supermoto Challenge with riders on identically prepared Honda CRF150Fs, and, beginning in 2005, Supermoto Lites for 200-250cc, four-stroke, single-cylinder motorcycles.
Racecourses were designed with approximately 80% pavement and 20% dirt, with jumps, whoop sections, and a flat-track-style turn. Courses were between .6 and 1.1 miles in length. Tabletop and Kicker "Urbancross" jumps were designed, fabricated, and then built on-site by ASD (a subsidiary of All-Access Staging and Productions) and these added an extra Motocross dimension to the paved portion of racecourses.
Unique to the AMA Supermoto championship were the use of temporary race venues in addition to traditional, purpose-built courses. Temporary venues such as Mazda Raceway Laguna Seca (unused portion of the racetrack and a parking lot), Reno (public streets), Columbus (public streets and parking lots) Dallas (Reunion Arena parking lot), Las Vegas (Rio Hotel parking lot and Bally's Casino parking lot), Copper Mountain (parking lot) were converted into racecourses complete with dirt sections and Urbancross ramps. Kart tracks (Miller Motorsports Park, Road America, USA International Raceway ) were also used as the tight, winding circuits lend themselves nicely to the agility of Supermoto motorcycles. Dedicated racecourses (oval automobile courses with infield road courses) were also used. Examples include South Boston Speedway, Irwindale Speedway, and Music City Motorplex.
