The Suzuki Hayabusa (or GSX1300R) is a sport bike motorcycle made by Suzukisince 1999. It immediately won acclaim as the world's fastest production motorcycle, with a top speed of 188 to 194 miles per hour (303 to 312 km/h).

In 2000, fears of a European regulatory backlash or import ban^[6][7][8] led to an informal agreement between the Japanese and European manufacturers to govern the top speed of their motorcycles at an arbitrary limit.^[9] The media-reported value for the speed agreement in miles per hour was consistently 186 mph, while in kilometers per hour it varied from 299 to 303 km/h, which is typical given unit conversion roundingerrors. This figure may also be affected by a number of external factors,^[10] as can the power and torque values.
