For 2014/2015 race season the ISR requires a Rev Limiter in all 120 stock class racing. The rule was put into place to equalize the engine RPMs between brands. 6850 rpm will be the limit setting.This was a long time request by many of the 120 racing groups, and was a combined effort with the manufactures and the ISR in order to create a fair playing field for all racers. The Rev Limiter will be powered by a 9 volt battery and be a simple 3 wire hook up.
NOTE: CONTACT YOUR RACING CIRCUIT FOR ANY GEARING CHANGES.
