Club100 is a UK-based "hire kart" karting championship. Senior/Junior karts use identical BirelART chassis, Rotax Junior Max 2 stroke engines and Dunlop KE1 tyres, while the Cadet championship use a smaller BirelART chassis, a smaller Rotax Micro Max 2 stroke engine and Dunlop SL3 tyres, these are provided by the club to an equal standard, putting all competitors on a level playing field.
History Club100 was established in Streatham, London, in 1993 by Martin Howell—the founder of the first indoor kart circuit—and John Vigor. It began as a six-round series at Buckmore Park. For 2019, Club100 replaced their fleet of TKM karts with Rotax karts, utilising their "Evo" technology and ending a 26-year tenure of Club100 using TKM machinery. Initially a senior and junior series, it launched a cadet championship under Vigor's management in 2021. By 2023, Club100 was the largest karting competition in the world. Club100 became a member of Motorsport UK (MSUK) in 2020, the Association of British Kart Clubs (ABkC) in 2021, and a founding member of the Rotax Racing Club (RRC) in 2026, which was founded to "replicate [the success of Club100] worldwide". It organised the inaugural RRC International Finals at Silverstone in 2026, which was described by Fabio Marangon of Vroomkart as "an organisation worthy of a World Championship".
