Tyres: Dunlop SL1

Ages 16 & above. Engines do not have restrictor plates and still use Dunlop SL1 tyres. This class provides close competition as all karts are closely matched and the lower output of the engine requires the development of a smooth driving style to maintain good cornering speeds. This class is still the most economical Senior class to compete. Engine modification and generally the lower output means engineslast longer between rebuilds.
