Sidecar Motocross is a sport where teams of two race motorcycles outfitted with sidecars on an earthen track. The driver and passenger work together in order to maneuver the motorcycle around the track's curves.

Sidecar motocross is very similar to regular motocross but with a different type of motorcycle chassis, and with a team of two people riding together instead of one. Sidecar motocross is carried out in the same way as regular motocross on very the same tracks. Handling is different due to the sidecar. Thus the driver cannot lean over in the turns to overcome the centrifugal forces, instead, to make sure the sidecar does not flip over, the passenger leans out (of the sidecar) as much as possible in the corners. The passenger does much more physical work than the driver since they move their whole body around continuously. A World championship is held over several rounds at top motocross venues, throughout Europe, with a season ending Sidecarcross des Nations. The sport is extremely popular in Eastern Europe. There is a much smaller scene in North America and Australia. The most successful sidecar motocrosser in history is the Dutchman Daniël Willemsen, who has become world champion six times so far. The most successful team in history however is Kristers Sergis / Artis Rasmanis, since Willemsen won his six titles with four different passengers.

The goal of sidecar motocross is to finish the motocross race in the fastest time.

One of the most important aspects of sidecar racing is teamwork; the best sidecar teams in the world have been racing together for many years so much of the training not only focuses on learning how to handle the sidecar, but also in developing the level of teamwork needed to be successful in the sport.
