Classes - Bitumen Track Karting

This section looks at the basics of getting started in the sport, like choosing a class. We have also included a guide of suitable chassis's available for each class.

The first step in getting into karting is to determine what class you would like to race. The three things to look at when choosing your class are :

  • The age of the driver ( 6 year olds can practice, competition starts at 7 years old. )
  • The weight of the driver
  • What your budget is for the sport, including set-up and on-going running costs. Karting is the cheapest form of motorsport.

There are four main classes and then sub classes depending on the engine you choose to run. The main classes are as follows:


 Class  Age Weight (kart + driver)  Number of Sub-classes 
 Cadet 9  6 - 9  from 90kg  1
Cadet 12  9-12  from 105kg  1
 Junior  12-16  from 120kg  5
 Senior   15 + from 140kg  14
