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.
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.
[1] When developments in dolphin and dustbin fairings on solo machines proved successful at reducing drag, it was natural to adapt similar streamlined enclosures for the sidecar outfits.
A pioneer in this area was Eric Oliver who worked with the Watsonian company on the development of successive experimental racing outfits including such innovations as the use of 16 in (410 mm) diameter wheels.
It began when George O'Dell won the championship using a Hub-center steering sidecar (built by Rolf Biland) called the Seymaz.
O'Dell won despite the Seymaz being rarely raced during the season in favor of using a traditional Windle frame for much of the year.
In 1980, due to the revolutionary changes being made by the constructors to their designs, the FIM banned all sidecar prototypes because it was concerned that the developments were turning passengers into non-active participants, and the machines were ceasing to resemble motorcycles.
Likewise sidecars that are outside of the technical rules are permitted to compete in races but their results, points or finishes are not recorded.
All chassis are purpose built and owe more to open wheel race car technology and the tires are wide and have a flat profile.
The most successful chassis is LCR, the Swiss sidecar maker, whose founder Louis Christen has won 35 championships between 1979 and 2016, with a variety of engines, originally Yamaha and Krauser two-strokes, more lately Suzuki four-strokes.
In 2014, for the first time a Kawasaki-powered machine won the title with Tim Reeves and Gregory Cluze ending an 11-year consecutive Suzuki run.
