Hot Cams Stage 1 Intake Racing Camshaft HC00059 for Yamaha YZ450F, YZ450FX and 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!

Upgrade your Yamaha performance with the Hot Cams Stage 1 Intake Racing Camshaft, manufacturer part number HC00059 and vendor part number HC00059. Designed for race-focused applications, this high-performance 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, and stronger throttle response across the operating range.

The Hot Cams HC00059 camshaft is engineered to improve engine feel and rider control without requiring a core exchange. In most applications, it is designed for use with the stock valve springs and rocker arms, making it a practical performance upgrade for compatible Yamaha four-stroke models. This Stage 1 intake camshaft is intended for riders seeking sharper response and improved performance on the track or in competition.
