Building upon the successful line-up of Vortex ROK engines, ROK Cup Promotions has launched the brand new Vortex ROK VLR. The perfect platform for the entry-level driver, the ROK VLR not only offers superior performance over its rivals with lower maintenance, but it also offers some great features like electric start all at a cost racers can afford.

The new ROK VLR engine comes complete, ready to race minus the engine mount (0 degree recommended). Approved for the O2s Championship, ROK Cup USA, and several other series.
