World's Fastest Motorcycle: It's the most prestigious title in motorcycledom, and an accolade that Mike Akatiff has been obsessed with since 2006. That was the year he and rider Rocky Robinson held that honor for two days before losing it to Denis Manning and Chris Carr. The World's Fastest title has been regained by Akatiff, however, following last September's Top Oil World Land Speed Shootout at the Bonneville Salt Flats. There, Robinson rode the Ack Attack streamliner to an amazing 360.913-mph average speed, crushing Carr's 350.884-mph mark by more than 10 mph. Covering nearly the length of two football fields per second, that's very fast indeed.
