Hot Cams Stage 1 Racing Camshaft 2041-1IN for Kawasaki KX250F and Suzuki RM-Z250

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 engine response and track performance with the Hot Cams Stage 1 Racing Camshaft, manufacturer part number 2041-1IN and vendor part number 68-2031. Developed with Hot Cams Improved Throttle Response (ITR) technology, this high-performance camshaft uses carefully engineered opening ramps to improve intake charge quality and combustion efficiency. The result is sharper throttle response, stronger engine feel, and improved rider control across the throttle range.

This racing camshaft is designed for fitment on 2004–2010 Kawasaki KX250F models and 2004–2006 Suzuki RM-Z250 models. The Stage 1 profile is designed to work with stock valve springs and rockers in most applications, helping simplify installation while delivering a performance-focused upgrade. No camshaft core is required. Adjustable cam sprockets are supplied with some applications, so verify the application details and included components before installation.

Feature-focused engineering makes the Hot Cams 2041-1IN a practical choice for riders and builders seeking improved responsiveness without sacrificing controllability. Professional installation, accurate timing, and careful clearance checks are recommended to ensure proper operation. This product is intended for racing and off-road use. It is not legal for use in California on pollution-controlled vehicles; race-use waiver requirements may apply.
