Grand Prix motorcycle racing is the premier championship ofmotorcycleroad 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, andSidecar.[1] The premier class is MotoGP, which was formerly known as the 500cc class.[1] The Grand Prix Road-Racing World Championship was established in 1949 by the sport's governing body, theFédération Internationale de Motocyclisme (FIM), and is the oldest motorsport World Championship in existence.[2] The motorcycles used in MotoGP are purpose-built for the sport, and are unavailable for purchase by the general public because they cannot be legally ridden on public roads.[2] From the mid-1970s to 2002, the top class of GP racing allowed 500cc with a maximum of four cylinders, regardless of whether the engine was atwo-stroke orfour-stroke.[2] Rule changes were introduced in 2002, to facilitate the phasing out of two-stroke engines.[3]

The number of points awarded at the end of each race to the top 15 qualifying riders depends on their placement.
