Superkarting for everyman, The Aussie Way

In the mid 1980s all gearbox karts in Australia moved under the control of CAMS (the Australian Auto Raceing Governing body) to race only on long (car) circuits.

Four main gearbox classes were developed: 80cc, 125cc, 250 cc single and 250cc twin cylinders. Subsequently 100cc non-gearbox (NGB) karts were adapted for long circuit racing. Recently these have been superceded by the adoption of 125cc Rotax Max (NGB) sprint kart engines for superkarting.

Today all these classes are available, with the NGB classes offering the most economical entry into superkarting led by the fast growing long life rotax NGB superkart community.

These Karts make top speeds from 170km/h for the Rotax NGBs up to 240km/h for the 250cc twins.

Here is a breakdown:

For the Rotax Max fans there is also a specialty Rotax Superkart called the Hypermax.
