WE RACE ON THE TRACK, NOT THE DYNO! Most camshaft designs are developed only on a dyno. Good camshaft designs not only increase power, they also improve throttle response. However, more power and better throttle response is a difficult design problem. Hotcams’ ITR technology solved this dilemma through highly engineered opening ramps not found on other cams. Using ITR technology, the critical ramp area is designed to give your engine a cleaner intake charge and a more efficient combustion cycle, making your engine more responsive at all throttle openings and giving the rider better feel and control of the engine! You will notice the difference!
