Hot Cams Stage 3 Racing Camshaft 1056-3 for Honda CRF450R, CRF450X and TRX450ER

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 3 Racing Camshaft, manufacturer part number 1056-3 and vendor part number 1056-3, is a high-performance replacement camshaft engineered for race-focused Honda applications. Hot Cams’ Improved Throttle Response (ITR) technology uses carefully developed opening ramps to help deliver a cleaner intake charge, more efficient combustion, and sharper throttle response across the operating range. The result is improved engine feel and greater rider control on the track or trail.

This Stage 3 camshaft is designed for riders seeking increased performance beyond a standard camshaft setup. Its racing profile is developed to improve power while maintaining responsive engine behavior, helping the engine react more effectively at varying throttle openings. The camshaft is supplied without requiring a core exchange and is designed to work with stock valve springs and rockers in most applications. Adjustable cam sprockets may be supplied on select model applications.

Fitment includes the 2002–2006 Honda CRF450R, 2005–2007 Honda CRF450X, and 2006–2007 Honda TRX450ER Electric Start. Verify the exact year, model, valve-train configuration, and installation requirements before ordering. Professional installation and proper cam timing are recommended to help ensure reliable performance and correct engine operation.
