Kart racing or karting is a motorsport discipline using open-wheel, four-wheeled vehicles known as go-karts or shifter karts. They are usually raced on scaled-down circuits, although some professional kart races are also held on full-size motorsport circuits. Karting is commonly perceived as the stepping stone to the higher ranks of motorsports, with most Formula One drivers—including Ayrton Senna, Michael Schumacher, Fernando Alonso, Kimi Räikkönen, Lewis Hamilton, Sebastian Vettel, Nico Rosberg, and Max Verstappen—having begun their careers in karting.

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 tires and wheels and most often race on full size auto-racing circuits.
