Harley-Davidson announced new Street 750 motorcycle hits the ice at the X Games in Aspen, Colo. Harley has partnered with ESPN to feature motorcycle ice racing as an X Games exhibition sport. The company modified several Street bikes by adding steel screws to the tires, and it will use flat-track racers to run the bikes on ice at high speeds.

The exhibition race will feature Harley-Davidson's Brad Baker, the reigning AMA Pro Grand National Champion, and several other elite flat-track racers.
