[3] The Sidecarcross World Championship, first held in 1980 and organised by the Fédération Internationale de Motocyclisme, is an annual competition.

[1][3] Sidecarcross is similar to motocross except that the teams consist of two riders, a driver and a passenger.

Races are held on the same tracks as solo motocross but the handling of the machines differs as sidecars don't lean.

The majority of physical work in the sport is carried out by the passenger, who speeds up the sidecarcross in corners by leaning out.

The riders placed seventh and eighth remain in reserve should one of the qualified teams not be able to participate.

[7] The FIM stipulates that all drivers must be of a minimum age of 18 while passengers have to be at least 16 years old to compete, but no older than 50.
