Streamliner designer Mike Ackitiff and rider Rocky Robinson opened a new era in motorcycle land speed racing, knocking down a 16-year-old mark and setting a new world record of 342.797 mph at the AMA/FIM International Motorcycle Speed Trials Sunday on the famed Utah Bonneville Salt Flats. The mark bests the old record, set by Dave Campos in a dual-Harley-Davidson-engined Easyriders Streamliner, by nearly 20 mph.
Riding a dual-Suzuki-Hayabusa-engined streamliner conceived and built by Ackitiff and dubbed "Ack Attack," Robinson took off for his first run on the 11-mile course on the salt, spun the wheels a bit, and then cooly notched a speed through the measured 1-mile traps of 344.673 mph.
World records governed by the Federation Internationale de Motocyclisme require that a second run be completed in the opposite direction within two hours, with the average of both speeds standing as the record. The crew turned the motorcycle around in 55 minutes, aimed it down the course, and when the wind stopped, did a second run of 340.922 mph.
