Hot Cams Stage 1 Racing Camshaft 2040-1E 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!

The Hot Cams Stage 1 Racing Camshaft, manufacturer part number 2040-1E and vendor part number 68-2032, is a high-performance replacement camshaft engineered to improve throttle response, engine feel, and usable power. Designed with Hot Cams Improved Throttle Response (ITR) technology, this camshaft uses carefully developed opening ramps to promote a cleaner intake charge and a more efficient combustion cycle. The result is more responsive engine performance across the throttle range, helping riders maintain better control on the track.

This racing camshaft is designed for select 250cc motocross applications and is compatible with the 2004–2010 Kawasaki KX250F and 2004–2006 Suzuki RM-Z250. It is intended as a performance upgrade for race-focused engine builds and is designed to work with stock valve springs and rockers in most applications. No camshaft core is required, and adjustable cam sprockets are supplied with some applications. Verify the motorcycle model, year, and engine specifications before installation.

The Hot Cams Stage 1 camshaft is intended for competition use and is not legal for use in California on pollution-controlled vehicles. California use is limited to racing applications, with a waiver available where applicable.
