Rotax Light and Heavy Classes:


It’s very easy to convert your current KartSport New Zealand compliant sprint kart to SuperKart specifications. All the sprint karting technical specifications are exactly the same for SuperKarting. There are five steps involved:



  1. Fit a 17 tooth front sprocket to your existing clutch drum. These are available from most Kart Shops and cost around $60.00. Start with a 74 tooth rear sprocket but you may end up running anywhere between 72 to 77 teeth depending on the conditions and the track.
  1. Fit a rain light and waterproof switch: These are available from most Kart Shops or Repco and cost around $70.00. A red rain light is mandatory. It must be a Narva LED trailer stop/tail lamp, part number 93816BL mounted horizontally. The brighter brake light circuit of the lamp must be used. In operation the light must be static. It must be powered by a fully sealed 12 volt battery that complies with KSNZ rule K1.37 and is controlled by a waterproof switch fitted within 150mm of the steering wheel. For Rotax Max and Rotax DD2 classes it is a permitted option to power the rain light by a second fully sealed 12 volt battery that complies with KSNZ rule K1.37. The light must be placed in an area located 400-600mm from the ground and 100mm maximum from either side of the central axis of the kart and must be rear facing and clearly visible by following karts. It must be in good working condition throughout the event displaying maximum light output. It must be switched on when the race is declared “wet” by the Clerk of the Course and is recommended to be switched on in any conditions where visibility may be reduced. The Chief Steward’s decision on the suitability and effectiveness of the rain light will be final.
  1. Put a bigger main jet in your carburettor. A 125 is usually about right.
  1. A front fairing is definitely an advantage when it comes to cutting through the air at higher speeds but it is not mandatory for SuperKarting. You can use your standard sprint racing nose cone and Nassau panel and a lot of people do this for their first SuperKarting event. A front fairing kit costs around $750.00 and comes with a custom mounting kit designed to fit your make and model of chassis. They are available in either black or white finishes from Tony at BM Fabrications in Auckland, phone: 027 278 7818 or bmfabrications10@gmail.com
  1. Put a black cross on your rear number plate. You will be required to run a cross on your rear number plate and leave your rain light on whenever you are on track until you have been observed by a KartSport New Zealand official and gained a Road Racing B Rated Non- Gearbox rating on your KartSport New Zealand licence.


Minimum all up weights are the same as sprint racing ie: 165kg for Rotax Light and 185kg for Rotax Heavy. Fuel and tyres are also governed by the same rules as sprint racing. If you need any help there is always a friendly committee member ready to answer any questions that you may have (See the contacts page).  

DD2 Class:


It’s very easy to convert your current KartSport New Zealand compliant sprint kart to SuperKart specifications. All the sprint karting technical specifications are exactly the same for SuperKarting. There are five steps involved:



  1. Fit a road race optional gear set to the engine (41/42 or 43/55) depending on the conditions and the track. These are available from most Kart Shops and cost around $520.00 a set.
