• 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 you're looking for that competitive edge, look no further than our Race Series. These exhaust systems are designed with nothing but power in mind. Each Race Series system is developed in accordance with noise compliance regulations imposed by most racing sanctioning bodies worldwide.
