MotoGP
Road Racing World Championship Grand Prix is the premier championship of motorcycle road racing. It is currently divided into three classes: MotoGP, Moto2 and Moto3. All three classes use four-stroke engines. In 2010, 250cc two-strokes were replaced by the new Moto2 600cc four-stroke class. In 2012, 125cc two-strokes were replaced by the Moto3 250cc four-stroke class with maximum weight limit 65 kilos with gas, and the engine capacity for MotoGP increased from 800cc to 1000cc.Grand Prix motorcycles are purpose-built racing machines that are neither available for purchase by the general public nor can be ridden legally on public roads. This contrasts with the various production-based categories of racing, such as the Superbike World Championship, that feature modified versions of road-going motorcycles available to the public.
