SUPERKART CLASSES

While Sprint kart racing competes through various classes at custom designed kart tracks, Superkart racing is a high-speed thrill ride at full motor racing circuits. Whether you're racing a highly customised International class kart, or modifying your Sprint kart with additional aerodynamic and safety features, Superkart racing is an experience not to miss. 

If you think Superkart racing looks quick in videos, wait until you see the action trackside! For more information on how to get involved in Superkart racing and the safety precautions/training required, please get in touch with the Superkart Drivers Club.​​​​​​​
