Hot Cams Stage 2 Racing Exhaust Camshaft HC00062 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!

The Hot Cams Stage 2 Racing Exhaust Camshaft, manufacturer part number HC00062 and vendor part number HC00062, is designed for high-performance Yamaha off-road motorcycles. Developed with Hot Cams Improved Throttle Response (ITR) technology, this racing camshaft uses carefully engineered opening ramps to improve intake-charge control, combustion efficiency, throttle response, and rider control across the operating range.

The HC00062 camshaft is designed for competition applications and is intended to work with stock valve springs and rockers in most applications. No core is required. The camshaft is supplied as an exhaust camshaft for compatible Yamaha models and may require proper installation, valve clearance adjustment, and engine timing verification by a qualified technician. Adjustable cam sprockets are supplied with some model applications.

Fitment includes the 2016 and 2017 Yamaha YZ450FX, the 2016 through 2018 Yamaha WR450F, the 2018 and 2019 Yamaha YZ450F, and the 2018 and 2019 Yamaha YZ450FX. Verify the motorcycle model year and engine configuration before installation.
