Grand Prix motorcycle racing is the premier championship of motorcycle road racing, which has been divided into three classes: MotoGP, Moto2, and Moto3. Former classes that have been discontinued include 350cc, 250cc, 125cc, 50cc/80cc, MotoE, and Sidecar. The premier class is MotoGP, which was formerly known as the 500cc class. The Grand Prix Road-Racing World Championship was established in 1949 by the sport's governing body the Fédération Internationale de Motocyclisme (FIM), and is the oldest motorsport world championship in existence. The motorcycles used in MotoGP are purpose-built for the sport, and are unavailable for purchase by the general public: they cannot be legally ridden on public roads. MotoE was introduced in 2019 as a "World Cup" until 2022 and thus statistics from that time span are not included here. MotoE only gained World Championship status from 2023 until 2025, because MotoE class went on hiatus after the 2025 season. This list also does not include winners from sprint races which were introduced in the MotoGP class in 2023.
