HOT CAMS Racing Cam Stage 1 for Yamaha YZ450F and WR450F (Part 4023-1IN)

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!

Enhance your Yamaha YZ450F or WR450F with the HOT CAMS Racing Cam Stage 1, designed for offroad performance enthusiasts seeking improved throttle response and engine responsiveness. This high-performance camshaft leverages advanced ITR technology to optimize intake ramp design, resulting in a cleaner intake charge and more efficient combustion cycle. The benefits include increased throttle response and better control, making your ride more predictable and exhilarating in competitive or trail settings. Built to be compatible with stock valve springs and rockers in most applications, this camshaft offers straightforward installation without the need for a core exchange. The package includes adjustable cam sprockets, allowing fine-tuning to match your engine’s specific needs, further enhancing performance and drivability. The Stage 1 camshaft is engineered specifically for Yamaha YZ450F and WR450F models from 2003 to 2009, ensuring a perfect fit and reliable operation. Designed for offroad use only, this camshaft is not legal for street or pollution-controlled environments in California, but a waiver is available for race applications. Whether you're looking for a competitive edge or an upgrade for your offroad adventures, the HOT CAMS Racing Cam Stage 1 delivers increased power, improved throttle response, and a more controlled engine feel, making it a valuable addition to your motorcycle's engine components.
