About the FIM (www.fim-live.com)
The FIM (Fe´de´ration Internationale de Motocyclisme) founded in 1904, is the world governing body for motorcycle sport and is an independent association formed by 101 National Federations throughout the world. It is recognised as the sole competent authority in motorcycle sport by the International Olympic Committee (IOC). Among its 49 FIM World Championships the main events are MotoGP, Superbike, Endurance, Motocross, Supercross, Trial, Enduro and Speedway. The FIM also deals with non-sporting matters such as leisure motorcycling, mobility, transport, road safety, public policy and the environment. The FIM was the first International Sporting Federation to enforce an Environmental Code in 1994.
