World championship

A world championship is generally an international sports competition open to elite competitors from across the world, representing their nations, and winning such an event will be considered the highest or near highest achievement in the sport or contest.

The title is usually awarded through a combination of specific contests or, less commonly, ranking systems (e.g. the ICC Test Championship), or a combination of the two (e.g. World Triathlon Championships in Triathlon). This determines a 'world champion', who or which is commonly considered the best nation, team, individual (or other entity) in the world in a particular field, although the vagaries of sport ensure that the competitor recognised at the best in an event is not always the 'world champion' (see Underdog).

Certain sports do not have a world championship, instead they may organise a world cup competition, or they may organize both. Often, the use of the term cup or championship in this sense is just a choice of words. Some sports have multiple champions because of multiple organizations such as mixed martial arts, boxing and wrestling.

List of Grand Prix motorcycle racing World champions

Grand Prix motorcycle racing is the premier championship of motorcycle road racing, which has been divided into three classes since the 1990 season: 125cc, 250cc and MotoGP. Classes that have been discontinued include 350cc and 50cc/80cc. 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.

There were four classes when the championship started in 1949; 500cc, 350cc, 250cc and 125cc. The 50cc class was introduced in the 1962 season. Due to escalating costs that resulted in a number of manufacturers leaving the championship, the FIM limited the 50cc bikes to a single cylinder, the 125cc and 250cc bikes were limited to two cylinders and the 350cc and 500cc bikes were limited to four cylinders. The 350cc class was discontinued in 1982; two years later the 50cc class was replaced with an 80cc class, which was discontinued in 1989. In 2002, 990cc bikes replaced the 500c bikes and the class was renamed as MotoGP. 600cc bikes replaced the 250cc bikes in the 2010 season, with the class re-branded as Moto2.
