Hot Cams Stage 2 Racing Camshaft 4280-2IN for 2014-2015 Yamaha YZ450F

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!

Upgrade your 2014 or 2015 Yamaha YZ450F with the Hot Cams Stage 2 Racing Camshaft, manufacturer part number 4280-2IN and vendor part number 4280-2IN. Developed for high-performance racing applications, this camshaft is engineered to increase power while improving throttle response and rider control across the usable throttle range.

Hot Cams Improved Throttle Response (ITR) technology uses carefully engineered opening ramps to promote a cleaner intake charge and a more efficient combustion cycle. The result is a more responsive engine with improved feel at all throttle openings. Unlike camshaft designs developed solely on a dyno, the Stage 2 camshaft is intended to deliver practical performance benefits on the track, including stronger response and enhanced engine control.

Fitment: This camshaft fits 2014 Yamaha YZ450F and 2015 Yamaha YZ450F models. It is designed to use stock valve springs and rockers in most applications, and no core is required. Adjustable cam sprockets are supplied with some model applications. Verify model-year compatibility and installation requirements before ordering.
