The ultra-aerodynamic Hayabusa is dominant on longer courses as well. The East Coast Timing Association organizes top-speed trials on an abandoned airstrip in Maxton, North Carolina, which have become almost the exclusive domain of 'Busa jockeys. The ultimate top-speed record-an amazing 260 mph-is held by-what else?-a stock-wheelbase, street-legal, Mr. Turbo-motivated Hayabusa, owned by Rich Yancy and ridden by Lee Shierts. That jaw-dropping speed was achieved, by the way, in the standing-start mile. On a longer track such as the 11-mile "long" course at the Bonneville Salt Flats, the Ack Attack streamliner, powered by a pair of Hayabusa engines, held until very recently the ultimate motorcycle land speed record of 342 mph.
