The Yamaha YZR-M1 is an inline-four motorcycle specifically developed by Yamaha Motor Company to race in the current MotoGP series.[1] It succeeded the 500 cc (31 cu in) YZR500 by the 2002 season and was originally developed with a 990 cc (60 cu in) engine. Since then, the YZR-M1 has been continuously developed into several iterations through the 990cc, 800cc and 1000cc eras of Grand Prix Motorcycle Racing.
