context_page_description: Grand Prix motorcycle racing is the premier class of motorcycle road racing events held on road circuits sanctioned by the Fédération Internationale de Motocyclisme. Independent motorcycle racing events have been held since the start of the twentieth century and large national events were often given the title Grand Prix. The foundation of the Fédération Internationale de Motocyclisme as the international governing body for motorcycle sport in 1949 provided the opportunity to coordinate rules and regulations in order that selected events could count towards official World Championships. It is the oldest established motorsport world championship.
  Grand Prix motorcycles are purpose-built racing machines that are unavailable for purchase by the general public and unable 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 current top division is known as MotoGP since 2002 when the four-stroke era began.
context_section_description: Moto2 was initially a 600 cc four-stroke class introduced in 2010 to replace the traditional 250 cc two-stroke class. Engines were supplied exclusively by Honda, tyres by Dunlop and electronics are limited and supplied only by FIM-sanctioned producers. Carbon brake discs are banned, only steel brake discs are allowed. However, there are no chassis limitations. Until 2019, only 600 cc four-stroke Moto2 machines were allowed.
  In 2019 Triumph replaced Honda as the sole supplier of Moto2 engines. The Triumph's engine configuration is 765 cc displacement with three cylinders, contrasting with the previous Honda's 600 cc in-line four.
