The history of Flat Track Motorcycle racing was built on the dirt tracks of America. The sport that became even more popular with 1971's motorcycle movie On Any Sunday, and it's highlighting of Champion Mert Lawwill had already been a favorite spectacle at county fairs and dirt tracks across the United States. This is a sport that features man and machine, coupled together in a poetic dance on the edge of beauty and disaster. On some tracks riders reach speeds of 130 m.p.h. before pitching the bike sideways into a left handed turn. Racers pass within inches or less of each other, darting high and low to gain an inch of ground in the name of their passion, and the glory of the checkered flag. This is America's original extreme sport, and now the Xtreem Flat Track Series will offer another great showcase for the world's top riders.
