HOT CAMS Racing Cam Stage 2 for Yamaha YZ250F – 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!

Upgrade your Yamaha YZ250F with the HOT CAMS Racing Cam Stage 2 (Part Number 4055-2E), engineered to deliver high-performance racing capabilities. This camshaft is designed specifically for offroad motorcycle applications and offers a significant boost in throttle response and engine efficiency. Featuring advanced ITR technology, the camshaft's highly engineered opening ramps ensure a cleaner intake charge and more efficient combustion cycle, resulting in a more responsive engine feel and improved rider control. Whether you're on the track or off-road, this camshaft helps maximize your motorcycle's performance by optimizing power delivery at all throttle positions.

Constructed to be compatible with stock valve springs and rockers in most applications, the HOT CAMS Racing Cam Stage 2 does not require a core and is easy to install. Some models come with adjustable cam sprockets, allowing fine-tuning for optimal performance and tuning preferences. Designed for competitive riders and enthusiasts alike, this camshaft is suitable for Yamaha YZ250F models from 2001 through 2010, ensuring a perfect fit for a decade of racing history.
