Motorcycle sport / Grand Prix motorcycle racing: Road Racing World Championship Grand Prix is the premier championship of motorcycle road racing. It is divided into three classes: 125cc, Moto2 and MotoGP. Participants in the 125cc class use a two-stroke engine while those in the Moto2 and MotoGP use four-stroke engines. In 2010 the 250cc two-stroke was replaced by the new Moto2 600cc four-stroke class. 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 categories of racing, such as the Superbike World Championship, that feature modified versions of road-going motorcycles available to the public. -------------------------------------------------- 2012 Grand Prix motorcycle racing season: The 2012 Grand Prix motorcycle racing season will be the 64th F.I.M.
