Yamaha YZR M1 Concept Bikes
The Yamaha YZR-M1 is a four stroke motorcycle specifically developed by Yamaha Motor Company to race in the current MotoGP series. 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.
