The TOP 1 Ack Attack is a specially constructed land-speed record streamliner motorcycle that, , has held the record for world's fastest motorcycle since recording a two-way average speed of 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 . 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 Federation Internationale de Motocyclisme (FIM),〔(【引用サイトリンク】url=http://www.fim-live.com/en/sport/world-records-attempts/events/ )〕 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 Suzuki Hayabusa engines, using a single Garrett turbocharger, intercooled with dry ice at 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. == History == 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. Bonneville has remained the location for record-breaking attempts to this day. A number of motorcycles have taken advantage of the area's fast conditions to push the land-speed record higher and higher. In 1975, Don Vesco became the first rider to set a record exceeding 300 mph on his Yamaha motorcycle. Between 2006 and 2010, the TOP 1 Ack Attack and the BUB Seven streamliner have gone back and forth with the motorcycle land-speed record on five occasions. The current mark, recorded in the 2012 edition of the Guinness World Records, stands at 376.363 mph, set by the Ack Attack on September 25, 2010. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ack Attack」の詳細全文を読む スポンサード リンク
