Enduro RS4 Aluminum Slip On Exhaust

Description

The goal – improve power in every area we could while keeping the goal making the 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.

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

• Significant power gains with Slip-on
• A USFS spark arrestor is included

If your serious – it’s only Yoshimura. Proudly made in the USA!
