CLASSES WE RACE
The Jersey Kart and Motor Club run the following Motorsport UK regulated classes on race days
Bambino
Age: 6-8
The Bambino class uses a small, specially designed kart for 6 to 8 year olds with a petrol Comer C50 engine or the new MightE electric powertrain (new for 2024). The tyres are all weather Le Cont, meaning that separate slick and wet rain tyres are not required. Top speed approx 30mph. The new electric karts are more expensive to buy, but maintenance and running costs are likely to be lower than petrol.
This class is for 6-8 year olds, who must undertake special training and competency programme before sending for their Motorsport UK Kart Clubman Bambino licence for time trials.

Cadet & Intermediate
Ideal start for 8-13 year olds in Cadet (8-11 for Rotax Micro) on Intermediate (10-13). There are several engine options for Cadet and Intermediate. Cadet may use a 900mm or 950mm chassis, but only the 950mm chassis may be used in Intermediate.
900mm chassis (phasing out)
Age: 8-12
In Jersey we've historically run the 900mm chassis for the IAME Gazelle Cadet and Honda GX160 Cadet classes. We will continue to run these classes as long as the chassis are within their homologation date, but long term these will phase out eventually, possibly 2026, we don't know for sure yet.
