SCRUTINEERING: Prior to the start of each meeting, all karts are inspected for compliance with safety and class regulations. All classes have a minimum weight limit for the kart and driver and post race weigh-ins and motor inspections are a feature of all meetings.
These classes have very strict rules and regulations to limit the costs involved in competing and the mechanical knowledge required to be competitive.
MIDGETS - The purpose of this class is to teach young people to drive karts of restricted performance and limited costs. Ages 7-10 yrs.
ROOKIES -Ages 11 - 13 years. Kart engines are restricted and use the same model as the juniors. AKA manual covers the acceptable alterations.
JUNIORS -Ages 14 - 17 years. The NATIONAL CLASS for young drivers utilises a hard compound (slow wearing) tyre and a reliable Yamaha KT100J lOOcc engine. With tyres that last 6-8 meetings and motors that need infrequent rebuilds, it is a very economical class to run and allows the drivers to learn the skills of motor sport without the technical worries of advanced classes.
SENIORS -17 years and over. NATIONAL CLASS - Engines are restricted to Yamaha KT100J which must be maintained in standard form. Tyres are restricted to a hard compound rubber to give longer life, low cost racing. This class is particularly suitable to newcomers to the sport.
CLUBMAN CLASS - Engines are restricted to the Yamaha KT100S and also one brand of hard compound tyre. This motor gives slightly higher performance than that in the national class and is subject to limited alteration from original stock condition. This class is also suitable to new drivers allowing them to learn the basics of driving without the complications of motor and tyre variables.
Allows a choice of motors employing a reed valve arrangement. These motors
can be modified to a higher degree offering more power and the class uses
a designated tyre.
