Micro Max Kart

Kart racing organized under the MSA umbrella is divided into specific age, weight and speed categories to suit youngsters as they grow. This ensures a safe and exiting progression from 5 years old onwards – Micro Max is the second step on the ladder.

Micro Max is a step up from the Bambino class or ideal to start karting for larger 7-year olds and can be competed in until the end of the year in which you turn 11.

Using a de-tuned ROTAX 125 Junior Max engine @ 8 bhp and fitted to a 95cm “mini chassis” – designed for 7 to 13-year-old kids – this provides an easy to drive, easy to run and low running cost formula. Various makes of chassis are available in SA.

The winner of the Micro Max class will be invited to compete at the ROTAX Max Challenge Grand Finals. The prize includes the use of brand-new kart and engine drawn by raffle this ensures the fairest racing in karting. All tyres dry and wet, fuel, oil, tools, trolley, etc. are covered by this prestigious invitation.

The Rotax karting formula provides for a very easy and low-cost upgrade from Micro Max to Mini Max class when your driver is either too old or too heavy to continue in Micro Max.

Micro Max has a minimum all up weight of 105kg and uses durable Mojo C2 tyres.

Club, Regional and National racing – part of the RMC South Africa Karting National Championship Series. 

Pricing & Buying Advice

Used karts are a lower‑cost option. Prices may vary depending on the age of the kart — invest in race‑competitive, up‑to‑date equipment rather than outdated karts that need extensive repairs or upgrades.
