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 is engineered for riders seeking sharper throttle response and stronger performance from their Yamaha YZ250F. Manufacturer part number 4273-2E, this high-performance camshaft uses Hot Cams Improved Throttle Response (ITR) technology to optimize the valve-opening ramps and improve the engine’s intake charge and combustion efficiency.\u003c\/p\u003e\u003cp\u003eUnlike camshaft designs developed solely on a dynamometer, the Hot Cams Stage 2 camshaft is designed to deliver useful performance on the track, including improved response across the throttle range and enhanced rider control. The carefully engineered ramp profile helps the engine respond more cleanly and efficiently, providing a more direct connection between throttle input and engine performance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e This camshaft fits 2014, 2015, and 2016 Yamaha YZ250F models. It is designed for use with stock valve springs and rocker components in most applications, and no camshaft core is required. Adjustable cam sprockets may be supplied with select applications; verify application details before installation.\u003c\/p\u003e\u003cp\u003eThis Hot Cams racing camshaft is intended for competition use.
