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!

Richard N. ★★★★★

The stainless header and aluminum muffler bolted right up to my CRF450L without any cutting, and the weight savings are immediately obvious when you lift the rear end. It's got that deep, aggressive RS-4 tone that makes every trail ride feel like a proper race day, though I do wish the instructions

Elizabeth ★★★★★

Bolted it on this weekend and the welds are absolutely flawless, the stainless header and aluminum muffler combo looks race-ready under the bike. Fired up first kick and the tone is deeper than stock without being obnoxious on the trail. For an international model, this is exactly the serious upgrad

Eva ★★★★★

The build quality on this full system is impressive—the stainless header welds are clean and the aluminum muffler saved noticeable weight compared to stock. After installing it on my CRF450L, the throttle response feels sharper and the tone is deep without being obnoxious. Perfect for anyone wanting
