Tillotson T4 UK Series UK 2026

About

The Tillotson T4 UK Series is a one-make karting championship built around the globally recognised Tillotson T4 concept, offering tightly controlled, cost-conscious racing on some of the UK’s best kart circuits. Running dedicated Junior and Senior classes on identical T4 chassis and sealed 225cc four-stroke engines, the series puts the emphasis firmly on driver skill, consistency and racecraft rather than budget or technical advantage. With strong links to the wider international T4 ecosystem, including Nations Cup and European-level events, the UK Series provides an exciting pathway for ambitious club racers and newer drivers alike to experience high-quality competition in a professionally organised yet accessible environment.
