The TOP 1 Ack Attack is a specially constructed land-speed record streamliner motorcycle that, as of March 2013[update], has held the record for world's fastest motorcycle since recording a two-way average speed of 605.697 km/h (376.363 mph) on September 25, 2010 in the Cook Motorsports Top Speed Shootout at Bonneville Speedway, Utah. The Ack Attack's fastest one-way speed was officially recorded at 634.217 km/h (394.084 mph). This was the third time in four years the Ack Attack had broken the motorcycle land-speed record.
The record was confirmed and certified by the (FIM), which is the world's leading regulatory authority for motorsports racing. The Ack Attack's record was included in the 2012 Guinness World Records.
Designed and built from the ground up by Mike Akatiff, the Ack Attack's bullet-shaped chassis is made from chromoly tubing. The motorcycle streamliner is powered by two 1,299 cc (79.3 cu in) Suzuki Hayabusa engines, using a single Garrett turbocharger, intercooled with dry ice at 35 pounds per square inch (240 kPa) boost, which produce more than 900 horsepower, and runs on Mickey Thompson tires. While pursuing the land-speed record, the Ack Attack experienced a number of failed attempts, including runs which ended in spectacular crashes.
The first land-speed record for a motorcycle was unofficially set in the early 1900s by Glenn Curtiss in Yonkers, New York. His recorded speed was 64 mph. Curtiss continued to push the limits of speed at the time, and by 1907 he had more than doubled his own record, setting a new mark of 136.27 mph. This record stood for more than 20 years.
It was not until 1930, in Arpajon, France, that Curtiss's record was officially eclipsed when Joseph S. Wright rode 137.23 mph on his motorcycle.
From the 1930s through the mid-1950s a number of motorcycle riders pushed their motorcycles to set new land-speed records at different locations (mostly in Europe). By 1956, when riders began to flirt with, and ultimately exceed, the 200-mph mark, the record-setting attempts were taking place at the Bonneville Salt Flats in Utah.
