Hot Cams Racing Cam Stage 2 for Yamaha YZ450F 2003-2009 - Improved Throttle Response and Performance

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 Part Number 4090-2E Racing Cam Stage 2 is designed to enhance the performance of your Yamaha YZ450F motorcycle from 2003 to 2009. This high-performance racing camshaft is engineered to deliver increased power and improved throttle response, making it ideal for offroad racing enthusiasts seeking maximum engine efficiency. The camshaft features advanced ITR technology, which ensures a cleaner intake charge and a more efficient combustion cycle, resulting in better engine responsiveness at all throttle positions. This translates into a more controllable and predictable riding experience, allowing riders to maintain optimal power delivery during demanding offroad conditions.

Constructed without the need for a core, the Hot Cams Stage 2 camshaft is compatible with most stock valve springs and rockers, simplifying installation and reducing modification requirements. Some models include adjustable cam sprockets, providing further tuning flexibility to optimize performance based on your specific setup. Please note that this camshaft is intended for offroad use only and is not legal for use in pollution-controlled vehicles in California, although a waiver is available for race use. Designed specifically for Yamaha YZ450F models from 2003 through 2009, this camshaft offers a significant upgrade over stock components, enhancing throttle response and overall engine performance for competitive and recreational riders alike.

Whether you're racing or riding for recreation, the Hot Cams Racing Cam Stage 2 provides a reliable and effective way to maximize your engine’s potential.
