Hot Cams Stage 1 Racing Camshaft 4044-1E for Yamaha WR450F

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!

Improve engine responsiveness and throttle control with the Hot Cams Stage 1 Racing Camshaft, manufacturer part number 4044-1E and vendor part number 68-2070. Designed for high-performance applications, this camshaft uses Hot Cams Improved Throttle Response (ITR) technology to optimize the critical valve-opening ramp area. The result is a cleaner intake charge, a more efficient combustion cycle, sharper throttle response, and improved rider feel across the throttle range.

This Hot Cams racing camshaft is engineered for select Yamaha WR450F models, including 2003 through 2009 and 2011 through 2013 model years. It is designed to work with stock valve springs and rockers in most applications, making it a practical performance upgrade for compatible engines. No camshaft core is required, and adjustable cam sprockets are supplied with some applications. Verify the motorcycle model, year, and installation requirements before ordering.
