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\u003eUpgrade your engine’s performance with the Hot Cams Stage 2 Racing Camshaft, manufacturer part number 4055-2E and vendor part number 68-2053. Designed for Yamaha YZ250F applications from 2001 through 2010, this high-performance camshaft uses Hot Cams Improved Throttle Response (ITR) technology to enhance throttle response, engine feel, and rider control across the throttle range.\u003c\/p\u003e\u003cp\u003eUnlike camshaft designs developed solely for dyno power, the Hot Cams 4055-2E is engineered with carefully developed opening ramps that help promote a cleaner intake charge and a more efficient combustion cycle. The result is stronger engine response and improved throttle control for racing and other high-performance applications. This Stage 2 camshaft is designed to deliver increased performance while maintaining practical compatibility with stock valve springs and rockers in most applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e Fits 2001–2010 Yamaha YZ250F models.
