HOT CAMS Racing Cam Stage 2 for Yamaha YZ250F – Improved Throttle Response and Power

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 Racing Cam Stage 2 (Part Number: 4273-2E) is a high-performance camshaft engineered for offroad motorcycle enthusiasts who demand superior engine responsiveness. Designed specifically for Yamaha YZ250F models from 2014 to 2016, this camshaft leverages advanced ITR technology to optimize intake charge and combustion efficiency. This results in significantly improved throttle response and a more aggressive power delivery, giving riders enhanced control and confidence during high-performance riding.
Constructed without the need for a core, the HOT CAMS Stage 2 camshaft is compatible with stock valve springs and rockers in most applications, simplifying installation and maintenance. It includes adjustable cam sprockets on some models, allowing for fine-tuning to match your specific riding style or performance goals. The design focuses on delivering power without sacrificing reliability, making it suitable for serious offroad racing and recreational riding alike.

Whether you're looking to maximize your bike's performance on the track or improve throttle response for everyday offroad adventures, the HOT CAMS Racing Cam Stage 2 offers a significant upgrade over stock components, providing a more responsive and powerful engine experience.
