Cadet 12 Chassis
Chassis eligibility states a minimum wheelbase of 880mm. More common chassis used is a 900mm, newer chassis have wheelbase adjusters that will allow you to change the wheel base out to 940mm.The chassis should be manufactured from 28mm tube which suits lighter weight karts and drivers. The Cadets use a 30mm hollow rear axle that is designed for use with drivers in the 6-12 age group. There are many manufacturers of these ‘Cadet Karts’, you can choose from Arrow, Deadly, Monaco, CRG, Tony Kart, Kosmic, Ricciardo and many more. We suggest you look for a brand that is commonly raced in the Griffith Kart Club, this will ensure availability of spare parts and advice from other experienced club members.

The class can use The Yamaha KT100J engine fitted with a restrictor Even though this class can use the Yamaha KT100J, it is a good idea to consider the Vortex Mini-Rok. We have seen this engine on-track racing the KT100J and the Mini-Rok is significantly faster and will provide the driver with a competitive engine. Cadet 12 is the highest class you can use the Vortex Mini-Rok for. When progressing to the next class (KA4) this engine is not used.
