Sidecars

Sidecar racing, known as Sidecarcross has been around since the 1950s but has declined in popularity ever since mid?1980s. This variant is common in Europe, with a few followers in the United States, New Zealand, and Australia. The premier competition, the Sidecarcross World Championship, is contested on European tracks only and almost exclusively by Europeans. Motocross sidecars are purpose built frames that resemble an ordinary motocross-cycle with a flat platform to stand on attached to either side and a handlebar at waist height to hold on to. The side of the "chair" (slang for the platform) usually follows the side of the road the nation in question drives upon, but not always. The passenger balances the bike by being a counterweight, especially in corners and on jumps. It is driven on ordinary crosstracks. It is very physically demanding, especially for the passenger. This is reflected in most in the Swedish term for passenger, burkslav, roughly translated as trunk/body/barrel-slave. This name comes from the early sidecars where the platform looked like a real road-sidecar and not today's platform. The major frame builders today are VMC, BSU, AYR, EML and Woodenleg. Ordinary engines can be used, but size matters and two engines purpose built for sidecars exist, Zabel (Germany) and MTH (Austria) are most common. Four-strokes are getting more common, usually KTM (Austria). Sidecar-cross racing, also known as sidecar motocross, is very similar to regular, solo motocross but with a different type of motorcycle chassis, and with a team of two people riding together instead of one, a driv

r and a passenger. While not confirmed most articles seem to show Sidecarcross starting in the UK in the 1930s. Several sidecar manufacturers (for example VMC and EML) in Europe make special chassis which, except for the engine, wheels, plastics, and other components from commonly available large-bore motocross bikes such as the Honda CR500, Kawasaki KX500, and large KTMs. There are also specialised monster-size 2-stroke engines such as the MTH 630, and 700cc Zabel which are made just for sidecar motocross racing. The Zabel and MTH are currently the top engines in the World Championship. HOCOB manufacturer of VMC chassis won the FIM award for the best manufacturer motocross sidecar 2007.
