Hot Cams Stage 1 Racing Camshaft 4011-1 for 2001–2005 Yamaha YFM660R Raptor

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 2001–2005 Yamaha YFM660R Raptor with the Hot Cams Stage 1 Racing Camshaft, manufacturer part number 4011-1 and vendor part number 68-2066. Designed for racing applications, this high-performance camshaft is engineered to improve throttle response, engine feel, and power delivery across the usable throttle range. Hot Cams develops its camshaft profiles for real-world track performance rather than relying solely on dyno results.

The Stage 1 camshaft uses Hot Cams Improved Throttle Response (ITR) technology, featuring carefully engineered opening ramps that help promote a cleaner intake charge and more efficient combustion cycle. The result is a more responsive engine with improved control and throttle feel. The camshaft is designed to work with stock valve springs and rocker arms in most applications, making it a practical performance upgrade for compatible Yamaha Raptor models. No core is required, and adjustable cam sprockets are supplied with select applications where applicable.

Fitment includes the 2001, 2002, 2003, 2004, and 2005 Yamaha YFM660R Raptor. Verify vehicle application and installation requirements before ordering.
