Red Rider off-roads fans can not rejoice as Honda has now released their CRF450X. A serious offering to take on the 450cc off-road category. 

As soon as we got our hands on the CRF450X we rolled up our sleeves and went to work. The goal-improve power in every area we could while keeping the goal making the new 450X easier to ride in a variety of off-road conditions. We tailored the power delivery to give the machine more usable rideablity. Power is up and weight is down for a win-win situation for te new red off-road machine

Benefits for the 2019 CRF450X Yoshimura RS-4 system include:

  • Significant power gains with full system
  • Full system incorporates a more "tucked in " header design, making it less susceptible to damage. 
  • Header boasts a thicker 18 gauge spec that provides better protection in off-coad conditions
