As a follow-up to post from Aug. 27 (read: Bonneville: The Great White Dyno), last Saturday at the Bonneville Salt Flats in Utah, the Ack Attack Streamliner became the fastest motorcycle on the planet. Driver Rocky Robinson piloted his streamliner to a new world land speed record of 376.156 mph and a new kilo record of 376.363. Ack Attack’s exit speed was an awesome 394 mph!

The Bub 7 Streamliner — owned by Denis Manning and piloted by Chris Carr — was the former record holder with a speed of 367.382 mph. Now that Rocky Robinson is again the fastest motorcycle rider in the world, he says he’s setting his sights on becoming the first rider to reach 400 mph on two wheels.
