Hot Cams Stage 1 Racing Camshaft 4017-1 for Yamaha Bruin and Big Bear ATV

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 Stage 1 Racing Camshaft, manufacturer part number 4017-1 and vendor part number 4017-1, is designed to improve throttle response, engine feel, and overall performance on compatible Yamaha ATV applications. This high-performance camshaft uses Hot Cams Improved Throttle Response (ITR) technology, which incorporates carefully engineered opening ramps to promote a cleaner intake charge and a more efficient combustion cycle.

Developed for real-world racing performance rather than dyno numbers alone, this Stage 1 camshaft helps deliver stronger response across the throttle range and improved rider control. It is designed for use with stock valve springs and rockers in most applications, and no core is required. The camshaft fits 2004–2006 Yamaha YFM350BA Bruin 2WD [SRA], 2004–2006 Yamaha YFM350FA Bruin 4WD [SRA], and 2000–2003 Yamaha YFM400FB Big Bear 4WD [SRA] models. Verify the model year and drivetrain configuration before installation.
