Today's stadium Supercross events draw as many fans as NFL games. And, motorcycling's largest spectator sport also attracts an audience that is as passionately brand loyal as any NASCAR enthusiast. Why? The once humble sport of racing bikes in the dirt has evolved into a huge entertainment spectacle, with plenty of flash and a cult of personality on par with today's most popular sports. Young stars, such as Kawasaki sensation James Stewart - the first African American to win a major motorsports championship - are also inspiring legions of young fans with fearless acrobatics and superb athleticism. And, motocross is fueling fashion and pop culture trends, from clothing to product designs.But even before Tom Cruise optioned James Stewart's life story, motocross was a sport that demanded - and attracted - extraordinary personalities. For the first time ever, their stories are captured under one roof."Motocross America," the first-ever museum exhibit to show and tell the sport's evolution in the U.S., opens for a two-year run on July 14th at the Motorcycle Hall of Fame Museum, outside Columbus, Ohio. From the athletes to designers, from rare machines to innovative gear, and all the amazing stories that connect them, the 8,000 square foot exhibit is designed to educate, entertain and inspire. It even features a resource center for anyone who wants to get started in racing.
