*INTERNATIONAL MODELS ONLY. NOT FOR USE OR SALE IN USA.

International Red Rider dual sport fans can now rejoice over the Honda CRF 450L and X a serious offering to take on the 450cc Dual Sport, Off Road category.

As soon as we got our hands on the international CRF450L, we rolled up our sleeves and went to work. The goal - improve power in every area we could while keeping to the goal of making the new 450 easier to ride in a variety of off-road conditions. We tailored the power delivery to give the machine more controlled rideability.  Power is up and weight is down for a win-win situation for the new red off-road machine.

Benefits for the International 2019 CRF450 L and X Yoshimura RS-4 system include:

  • Significant power gains with this full system
  • Lambda/O2 sensor bung
  • Header pipe incorporates a "tucked in" design, making it less susceptible to damage
  • Header boasts a thicker 18 gauge spec that provides better impact-protection in off-road conditions

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

    Good exhaust, poor service parts delivery.

    I've the RS-4 Stainless Steel Full-System on my new Honda CRF450L 2019 and it is for sure away beter than the original Honda, more power at all rpm.
    But after 2 ~ 2,5 years it needs to be refilled so the noise gets a little bit less.
    Finally, after about 6 months I received this service RePack-Kit!
    Too bad was that the SparkPlug which I also want for the exhaust still isn't received!
    This very long delivery times are really annoying.

    I'm living in Europe the Netherlands
