No less than eight different brands of twin cylinder motorcycle will be competing in this weekends Grand National Championship Flat track race at the Yavapai Downs in Prescott, Arizona.
Run on a mile-long dirt-oval, similar to a giant speedway track, the 125bhp 750-1000cc twins will reach speeds of up to 140mph, clashing handlebars as they compete for the £100,000 prize money.
