Hot Cams Stage 3 Racing Camshaft 4098-3E for 2004–2009 Yamaha YFZ450

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 the performance of your Yamaha YFZ450 with the Hot Cams Stage 3 Racing Camshaft, manufacturer part number 4098-3E. Designed for high-performance racing applications, this camshaft uses Hot Cams’ Improved Throttle Response (ITR) technology to enhance engine response across the throttle range. Its engineered opening ramps help deliver a cleaner intake charge and more efficient combustion cycle, giving the rider improved throttle control, stronger response, and better engine feel.

The Hot Cams 4098-3E is designed to work with stock valve springs and rockers in most applications, and no camshaft core is required. Adjustable cam sprockets are supplied with some applications where applicable. This Stage 3 racing camshaft is specifically designed to fit 2004, 2005, 2006, 2007, 2008, and 2009 Yamaha YFZ450 models. Verify model-year compatibility and installation requirements before purchase.

Hot Cams develops performance camshafts with track-focused testing and engineering rather than relying solely on dyno results. The Stage 3 profile is intended for competition use where increased performance, throttle response, and rider control are priorities. Professional installation and appropriate valve clearance checks are recommended for best results.
