Several sidecar manufacturers (for example VMC, Wasp, 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.
