Thrilling two-wheel action heats up the track as some of the best motorcycle racing in the country will roar into town for its annual pilgrimage. MotoAmerica’s premier Superbike class headlines the weekend as riders jump aboard powerful Yamahas, Suzukis, Kawasakis, Ducatis and BMWs to carve their way through the technically-demanding 2.238-mile road course. New this year is MotoAmerica’s Heritage Cup that features vintage motorcycles from 1986 or earlier.
