VORTEX KIWI MINI ROK ​​​​​​​INFORMATION

The Vortex Kiwi Mini ROK engine powers our two youngest Age Group Classes, Cadet ROK and Vortex Mini ROK.

Transition between these classes is very simple and inexpensive with just a change of the plug in RPM Limiter (from 11,000 rpm to 14,000 rpm) and a swap of exhaust header required.

Vortex has produced a comprehensive Installation, Run In and Service Manual. The Manual includes a list of tools required, step by step instructions with pictures, run in guidelines, service recommendations, key torque settings etc.

NOTE: FUEL, Vortex recommend 95 octane (RON) minimum.

NOTE: Spec oil must be used. Please see the relevant class rules in Section E for the correct oils HERE
