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 system is designed for select Triumph TF450 models and features an aggressive, asymmetrical muffler profile. Developed and tested over more than three years, the RS-12 design maximizes muffler volume, manages sound, adds power, and provides increased clearance for the tire and brake caliper.

This system features precision-machined joints, a tapered muffler body inlet, and a works-look matte carbon fiber end cap with detailed decal inlays. The carbon fiber cap is designed to ease servicing compared with sandwich mounting designs commonly used in the industry. It also incorporates a patent-pending Precision Taper Fit (PTF) insert ring.
