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!\n\u003cp\u003eThe Hot Cams Stage 2 Racing Camshaft, manufacturer part number 4281-2E and vendor part number 4281-2E, is designed for riders seeking increased engine performance and sharper throttle response on the track. Developed with Hot Cams Improved Throttle Response (ITR) technology, this high-performance camshaft uses precisely engineered opening ramps to improve the intake charge and promote a more efficient combustion cycle.\u003c\/p\u003e\u003cp\u003eUnlike camshaft designs evaluated only for peak dyno output, the Hot Cams 4281-2E is engineered to deliver useful performance across the throttle range. The result is a more responsive Yamaha YZ450F engine with improved rider control and a stronger connection between throttle input and engine behavior. This Stage 2 racing camshaft is intended for competition applications and is built for demanding track use.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e This Hot Cams Stage 2 camshaft fits 2014 Yamaha YZ450F and 2015 Yamaha YZ450F models.
