WorldSBK - Yamaha YZF-R1

2009 YZF-R1

Launched in 2015 to global press acclaim, the Yamaha YZF-R1 proved itself on and off the track during its debut year, claiming victory in the Suzuka 8-hour endurance race as well as the British and American Superbike Championship Titles. Replicating the production motorcycle, the WorldSBK-Spec YZF-R1 is adapted for World Championship competition by removing road-safety aspects such as headlights and wing-mirrors, replacing bodywork with racing items and allowing modifications to engine management, exhaust systems, suspension, brakes and a number of engine parts. Current regulations stipulate the bike must weight a minimum of 168kg, with power ranging between 750cc and 1200cc, depending on the number of cylinders the engine contains, while the tuning of race machines is now subject to more limitations than in previous years due to the restriction of technical modifications.
