HOT CAMS Racing Cam Stage 1 for Yamaha YFM660FG Grizzly & Rhino 660 - High Performance ATV/UTV Engine Camshaft

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 YFM660FG Grizzly or YXR660F Rhino with the HOT CAMS Racing Cam Stage 1, part number 4100-1, designed for optimal performance in ATV and UTV applications. This high-performance racing camshaft features advanced ITR technology, which is engineered to enhance throttle response and improve engine responsiveness across all throttle positions. Unlike many other cam designs that are developed solely on a dynamometer, HOT CAMS’ innovative approach emphasizes real-world track performance, ensuring your vehicle delivers better power delivery, cleaner intake charge, and more efficient combustion. These improvements translate into a more engaging driving experience with increased control and feel during operation, making it ideal for racing or demanding off-road use.
