MotoGP is the premier class of Grand Prix motorcycle racing, the fastest and most prestigious branch of the sport. It is sanctioned by the FIM (Fédération Internationale de Motocyclisme), motorcycling's world governing body, and run commercially by Dorna Sports, the Madrid-based promoter. Grand Prix racing has crowned a world champion since 1949, making it one of motorsport's oldest world championships.
The bikes are purpose-built 1000cc four-stroke prototypes — machines you cannot buy in a showroom, capable of well over 350 km/h. Five manufacturers currently line up: Aprilia, Ducati, Honda, KTM and Yamaha. Each season they chase two titles — one for the best rider, one for the best constructor.
MotoGP also sits at the top of a three-class ladder. Moto2 (spec 765cc Triumph engines) and Moto3 (250cc single-cylinder bikes) are the junior categories, racing on the same weekends, and riders typically climb Moto3 → Moto2 → MotoGP. For a full breakdown, see how the three classes differ.
