The annual Rockerbox Motofest® is the premier Wisconsin motorcycle show and party featuring an eclectic mix of Euro, Japanese and American vintage café racers, choppers, sport bikes, racing machines, supermotos, scooters, and sidecars. All makes and models of bikes are welcome and you will find a mash of bikes competing for space alongside dealers and vendors of all things motorcycling. Rockerbox centers around a ride-in bike show and competition on Saturday with entrants from all over the country in competitive award classes showcasing the greatest in classic style, fresh customization and all that is unusual and incredible. Meanwhile, the grounds are packed with local and national vendors, live music, food, refreshments, a micro brew tasting, touring of the 4-mile road course, stunt shows, kart racing, and of course a slow speed evening sunset cruise of the road course. Friday, Saturday and Sunday the on-track activities feature vintage racing motorcycles from the 1920s to the early 70s and vintage superbikes from the 70s and 80s. The American Historic Racing Motorcycle Association (AHRMA) is dedicated to preserving the heritage of racing motorcycles and promotes this heritage through events at legendary race circuits. Road America is a track favorite of competitive vintage riders because of its four-mile layout including, high-speed straights, multiple turns and undulating terrain. Several passing areas contribute to the competitive spirit and racing action.
