The FIM Road Racing World Championship Grand Prix is the premier class of motorcycle road racing, held since 1949.
Grand Prix motorcycles are purpose-built racing machines that are neither available for purchase by the general public nor able to be ridden legally on public roads. This contrasts with the various production-based categories of racing, such as the Superbike World Championship and the Isle of Man TT Races that feature modified versions of road-going motorcycles available to the public.
The championship is currently divided into three classes: MotoGP, Moto2 and Moto3. All three classes use four-stroke engines. In 2010, 250 cc two-strokes were replaced by the new Moto2 600 cc four-stroke class. In 2012, 125 cc two-strokes were replaced by the Moto3 250 cc four-stroke class with a weight limit of 65 kg with fuel, and the engine capacity for MotoGP increased from 800 cc to 1,000 cc.
Previously, the championship featured a 50 cc two-stroke class from 1962 to 1983 and 80 cc from 1984 to 1989; a 350 cc two-stroke class from 1949 to 1982; and a 750 cc class from 1977 to 1979.
