After over three years in development and testing we are pleased to announce the RS-12 is here! With the help of incredibly talented factory sponsored athletes, technicians, devoted engineers and a will to raise the bar, our RS-12 has now arrived. We considered all the details when it came to the RS-12. One look and you can see it's like nothing else on the market. As you get closer you will notice the details in every place on our new dirt bike system, from the matte carbon fiber end cap with decal inlays to the precise machined joints, this system is next level.

The Yoshimura RS-12 Exhaust Race Slip-On SS/SS/CF, part number 123412S520, is designed for select Honda CRF300L and CRF300L Rally models. Developed and tested over more than three years, the RS-12 reflects Yoshimura’s focus on detailed construction, functional design, and performance-oriented development.

Its aggressive, asymmetrical RS-12 profile maximizes muffler volume, manages sound, adds power, and provides additional clearance for the tire and brake caliper. Precision machined joints and a tapered muffler body inlet contribute to the system’s carefully engineered construction.

The system features a works-look matte carbon fiber end cap with decal inlays and intricate detailing. The carbon fiber cap is designed to ease servicing compared with sandwich mounting designs commonly found in the industry. A patent-pending Precision Taper Fit (PTF) insert ring completes the RS-12 design.
