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 3 Racing Camshaft, manufacturer part number 4302-3IN and vendor part number 68-2186, is a high-performance camshaft designed for improved engine response and racing performance. Built for select Yamaha YFZ450R and YFZ450X applications, this camshaft uses Hot Cams Improved Throttle Response (ITR) technology to optimize the opening ramp profile and promote a cleaner intake charge.\u003c\/p\u003e\u003cp\u003eUnlike camshaft designs developed solely for dyno power, the Hot Cams Stage 3 profile is engineered to improve both power delivery and throttle response. Its carefully developed ramp area supports a more efficient combustion cycle, helping the engine respond more quickly across the throttle range while giving the rider improved feel and control. The camshaft is designed for competition use and is intended for riders seeking enhanced performance from compatible Yamaha engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e Fits 2009–2017 Yamaha YFZ450R models and the 2010 Yamaha YFZ450X. The camshaft is designed to work with stock valve springs and rockers in most applications, and no core is required. Adjustable cam sprockets are supplied with some models where applicable. Professional installation and verification of valve-train clearances are recommended before operation.\u003c\/p\u003e\u003cp\u003eThis Hot Cams racing camshaft is not legal for use in California on pollution-controlled vehicles.
