The 500cc World Championships was a premier motorcycle racing series that featured 500cc two-stroke motorcycles. It was part of the Fédération Internationale de Motocyclisme (FIM) Grand Prix motorcycle racing and ran from 1949 until 2002. This championship was known for its high-speed races and attracted top riders and manufacturers. The series showcased legendary racers like Giacomo Agostini and Mike Hailwood, who became icons in the sport. The 500cc class was eventually replaced by the MotoGP category, which continues to be the top level of motorcycle racing today, featuring advanced technology and higher performance bikes.
