Hot Cams Stage 1 Racing Camshaft 1058-1 for Honda TRX300EX Sportrax

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 engine response of your Honda TRX300EX Sportrax with the Hot Cams Stage 1 Racing Camshaft, manufacturer part number 1058-1 and vendor part number 68-2013. Designed for high-performance racing applications, this camshaft uses Hot Cams Improved Throttle Response (ITR) technology to enhance throttle response, engine feel, and rider control across the throttle range.

Unlike camshaft profiles developed solely for peak dyno power, the Hot Cams Stage 1 design incorporates carefully engineered opening ramps that help promote a cleaner intake charge and a more efficient combustion cycle. The result is sharper response and improved usability on the track. The camshaft is designed to work with stock valve springs and rockers in most applications, and no core is required. Adjustable cam sprockets are supplied with some applications where applicable.

This Hot Cams racing camshaft fits 1993–2002 Honda TRX300EX Sportrax models. It is intended for race use and performance-oriented applications.
