Karting Class Regulations

The Motorsport UK Karting Class Regulations provide detailed technical requirements for a range of karting categories and classes. On this page, you can access class-specific regulations covering Honda Senior, IAME S125, Junior Gearbox, Cadet, Rotax Max and Superkart classes, including 125 Open, 450 National and Division 1 Superkart.

These documents set out the rules you need to understand before preparing or entering a kart, including eligibility, chassis and engine requirements, permitted modifications, tyres, brakes, weights, number plates, safety equipment and age requirements. They should be read alongside the Motorsport UK Karting Yearbook and the National Competition Rules to help ensure each kart meets the correct technical standards for its class.
