Superkart

Superkart is a form of motorsport road racing that uses karts on long circuits. The bigger difference between a superkart and most other forms of kart is that they have full aerodynamic bodykits, as well as having a longer wheel base than sprint chassis, and are generally raced on car circuits over 1,500 metres in length. The power unit, most often but not exclusively two-stroke 250 cc engines, can be specially designed kart engines or production motorcycle engines with either five- or six-speed sequential manual gearboxes. Owing to their high top speed and superb cornering ability, a superkart's aerodynamic bodywork includes a front fairing, larger sidepods, and a rear wing. They use either 130-or-150-millimetre-diameter (5 or 6 in) tires and wheels and most often race on full size auto-racing circuits.

The 250 cc superkarts can set faster lap times than much more expensive and technically advanced racing machines.^[1][2] Some British and Australian classes also include 125 cc gearbox karts. Superkarts race on "long circuits"^[3] (e.g. Silverstone, Laguna Seca, Magny-Cours). In the UK they also race on "short circuits"^[4] (e.g. Kimbolton); "short circuits" are under 1,500 metres in length.^[5] Superkarts are raced worldwide. There is a multi-event CIK-FIA European Superkart Championship (for 250 cc karts only),^[6] and there has in the past been a world championship, which was last run in 1995.^[7]
