ChampionshipsTHE CHAMPIONSHIP EXPLAINED
Junior MAX
This is the step up from Mini Max or for new comers to start racing between 12 and 15* years old. Using the famous Rotax 125 Junior Max engine without restrictors (22 bhp), fitted to a 104cm “senior” chassis and wider Mojo D5 tyres and a minimum weight of 145 kg these karts set impressive lap times.
The Rotax karting formula provides for a very easy and low-cost upgrade/downgrade right from Micro Max up to Senior Max, so when your driver is either too old or too heavy to continue in Junior Max the engine can be upgraded to Senior Max specification (30 bhp).
New complete race-ready karts cost incl. VAT R 134 000 and used outfits sell for R 50 000 upwards (beware of buying outdated equipment with a view to renovating it – rather spend more and buy race competitive stuff).
These hi-tech water-cooled Rotax engines provide a very long life and parity of performance so you score from real long-term economy. Electric start and auto-clutch provide a safe and convenient way to get out there or recover from a spin without needing assistance.
