The AMA Grand National Championship stands as the ultimate level of competition for professional flat track racers. The Grand National Championship series features custom built race bikes using a variety of engine types, competing on mile, half mile, short track and TT courses.
Over the years, a number of motorcycle manufacturers have made their mark in this all-American series. However, none have been as successful as America’s largest manufacturer, Harley-Davidson. Since 1972, Harley-Davidson has captured a record 24 championships.
