FIM Sidecar World Championship is the international sidecar racing championship. It is the only remaining original FIM road racing championship class that started in 1949.
It was formerly named Superside when the sidecars moved from being part of Grand Prix Motorcycles racing to being support events for the Superbike World Championship. In 2010 the FIM took over the management of the series from the Superside promoters, and the championship was called "FIM Sidecar World Championship". However, the FIM still uses the word Superside for promotion purposes, despite the demise of the Superside promoters.
The championship is raced over a number of rounds at circuits mainly in Europe, although other venues have been included in United States ( Monterey), South Africa at Kyalami and Australia's Phillip Island.

who worked with the Watsonian company on the development of successive experimental racing outfits including such innovations as the use of diameter wheels.
Design changes
By 1953, motorcycle frames had undergone a complete redesign to accommodate the side car. Seat heights had been reduced to the point where the driver now sat in a semi-prone position. This permitted the use of a one-piece fairing which enclosed the front of the outfit as well as the sidecar platform. The enclosure led to unf
