Yoshimura RS-4 Full System

Red Rider off-road fans can now rejoice as Honda has now released their NEW CRF450X. A serious offering to take on the 450cc off-road category.

As soon as Yosh got their hands on the CRF450X they 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. They tailored the power delivery to give the machine more usable rideablity. Power is up and weight is down for a win-win situation for the new red off-road machine.

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

  • Significant power gains with slip-on and even more with the full system version
  • 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-road conditions
  • A USFS spark arrestor is included with slip-on and full system

If your serious - it's only Yoshimura. Proudly made in the USA!
