Vortex ROK DVS Introductory Offer and 

Junior Prize Drives Announced

A new era for New Zealand Karting is getting close and Supreme Kart Supplies & Engines is delighted to be the NZ distributor of the Vortex ROK DVS engine announced just prior to Christmas.

The Vortex ROK DVS is a state of the art water-cooled engine, but without all the complexity of batteries, starter motorsDVS_with_guard-clear (002).jpg and clutches, harking back to the simpler, lighter days of old. An engine that will offer Junior and Senior competitors a raw yet sophisticated karting experience with throttle response to match. The simplicity, technology and quality of the DVS engine far exceed that of the old Yamaha KT100. 

An exceptional service life combined with long term fixed performance control/rules make the ROK DVS an excellent engine choice. It will provide drivers with the stability they are looking for as there are no ongoing evolution costs and the engine’s excellent parity will provide a level playing field with regards to performance. The same simple philosophy as applied to the Vortex Mini ROK carburettor has been adopted for the DVS carburettor. This ensures that the tuning is very simple for everyone. Installation of the engine is also very straight forward.

If you are attending the 2018 City of Sails incorporating Round 1 of the 2018 ROK Cup Series at KartSport Auckland, 26-28 January, please call by our pit site and check out the ROK DVS engine which we will have mounted, ready to go, on a new Tony Kart chassis.
