Hot Cams Stage 2 Racing Camshaft 4054-2IN for Yamaha YZ250F

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 2 Racing Camshaft, manufacturer part number 4054-2IN and vendor part number 68-2054, is a high-performance intake camshaft designed for select Yamaha YZ250F models. It fits 2001–2010 Yamaha YZ250F motorcycles and is engineered to improve engine response, throttle control, and overall racing performance.

Hot Cams develops its camshaft profiles for performance on the track, not solely on a dynamometer. The Stage 2 cam uses Improved Throttle Response (ITR) technology, including carefully engineered opening ramps that help deliver a cleaner intake charge and more efficient combustion cycle. This design improves throttle response across the operating range, giving the rider enhanced engine feel and control at varying throttle openings.

The 4054-2IN camshaft is designed for use with stock valve springs and rockers in most applications, and no core is required. Installation and setup should follow the manufacturer’s specifications, with proper valve clearance and timing verification before operation. This camshaft is intended for racing use and is not legal for use in California on pollution-controlled vehicles; a race-use waiver may be available. Confirm engine configuration and application compatibility before installation.
