Hot Cams Stage 1 Racing Camshaft 2250-1E for Arctic Cat DVX 400 and Kawasaki KFX 400

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 performance with the Hot Cams Stage 1 Racing Camshaft, manufacturer part number 2250-1E and vendor part number 68-2021. Developed with Hot Cams Improved Throttle Response (ITR) technology, this high-performance camshaft uses carefully engineered opening ramps to promote a cleaner intake charge and more efficient combustion cycle. The result is stronger throttle response, improved engine feel, and better control across a broad range of throttle openings.

This racing camshaft is designed for select 400cc applications and is compatible with stock valve springs and rocker arms in most installations. No camshaft core is required, simplifying replacement and installation. Adjustable cam sprockets are supplied with some models where applicable. The Stage 1 profile is intended for riders and builders seeking improved performance while maintaining practical compatibility with standard valvetrain components.

Fitment includes 2004–2008 Arctic Cat DVX 400 models and 2003–2006 Kawasaki KFX 400 models, along with the 2003 Kawasaki KLX400R. Verify the exact year, model, engine configuration, and installation requirements before ordering. This Hot Cams product is intended for racing and off-road performance use.
