"EVC" (EXHAUST VELOCITY CONTROLLER) a progressively wound spring- EVC KTM's single rate power valve spring is replaced with the "EVC" (EXHAUST VELOCITY CONTROLLER) a progressively wound spring, specifically design to optimize the power across the full RPM range, also improving the valve response for much better recovery time jump landings and turn exiting. EVC provides over a 1HP (horse power) gain from 8000 RPM to 11000 RPM, and a .4HP boost through the rest of the power band. Improved lap times and clearing the double jumps are much easier not to mention increasing the fun factor!
