Hot Cams Stage 1 Racing Camshaft 4131-1 for 2009–2018 Yamaha YFM700R 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!

The Hot Cams Stage 1 Racing Camshaft, manufacturer part number 4131-1 and vendor part number 4131-1, is engineered for riders who want sharper throttle response and stronger performance from their Yamaha YFM700R Raptor. Rather than relying solely on dyno results, Hot Cams develops its camshaft profiles for real-world track performance, balancing power gains with improved engine feel and control.

Featuring Improved Throttle Response (ITR) technology, the 4131-1 camshaft uses carefully engineered opening ramps to help deliver a cleaner intake charge and more efficient combustion cycle. The result is more responsive engine behavior across the throttle range, allowing the rider to apply power more smoothly and control the engine with greater precision. This is a high-performance racing camshaft intended for competition and performance applications.
