Hot Cams Stage 1 Racing Camshaft 4022-1E for 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 engine’s throttle response and overall performance with the Hot Cams Stage 1 Racing Camshaft, manufacturer part number 4022-1E and vendor part number 68-2069. Designed for high-performance racing applications, this camshaft uses Hot Cams’ Improved Throttle Response (ITR) technology to optimize valve opening ramps and improve the intake charge. The result is a more efficient combustion cycle, stronger response across the throttle range, and improved rider control.

The Hot Cams Stage 1 camshaft is engineered as a direct performance upgrade for compatible Yamaha YZ450F models. It is designed to work with stock valve springs and rockers in most applications, and no core is required. Adjustable cam sprockets are supplied with some applications where specified. This camshaft is intended for competition use and is built for riders seeking sharper engine response without sacrificing practical installation compatibility.

Fitment includes the 2003–2009 Yamaha YZ450F. Verify the motorcycle model year and application before installation. This product is not legal for use in California on pollution-controlled vehicles and is intended for race use only in California; a waiver may be available.
