Hot Cams Racing Cam Stage 2 for Yamaha YZ450F with ITR Technology - Part #4166-2EX

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 #4166-2EX) is engineered to elevate your Yamaha YZ450F offroad performance. Designed with advanced ITR technology, this high-performance camshaft enhances throttle response and delivers a cleaner intake charge for more efficient combustion. Its innovative ramp design ensures your engine responds more precisely at all throttle levels, providing better control and a more engaging riding experience. This camshaft is ideal for riders seeking optimal power gains and improved responsiveness without the need for modifications to stock valve springs or rockers.
Constructed for durability and ease of installation, the Hot Cams Racing Cam Stage 2 is compatible with several Yamaha YZ450F models from 2010 to 2013. The kit includes adjustable cam sprockets in some applications, allowing for fine-tuning of the cam timing to suit your riding style.
