Category: Signature Series Exhaust System

The Triumph brand may be new to the Motocross world, but they are not strangers to building top-quality products and securing race wins. That legacy of performance and reliability is a perfect fit for Yoshimura. We are excited to bring performance enhancements to the new Triumph TF250X, TF250C, and TF250E.

Our now-iconic RS-12 Signature Series full system not only looks stunning on the TF250 but also delivers significant power gains across the entire spectrum. Riders can expect up to a 2.63% increase in horsepower at 11,600 rpm and torque improvements of up to 1.08% at 9,180 rpm.

Some of the features of the new RS-12 include:

Carbon Faced Machined Joint

Our new Carbon Faced Machined Joint no longer requires the use of anti-seize. This is accomplished by impregnating the surface of the stainless steel joint with carbon atoms. The result is a reduction in wear over the life of the joint by reducing friction.

Header Resonator

Our header resonator isn't just there for looks, it allows us to maximize power across the spectrum, while enhancing rider connectivity.

Experience the perfect combination of performance, style, and quality with Yoshimura’s latest exhaust system for the Triumph TF250.

Yoshimura's RS-12 is proudly designed, developed and manufactured in Chino, California.

Edward ★★★★★

Took it out for the first ride and the aluminum muffler keeps the weight noticeably low, which the bike needed. The stainless pipes already have a nice deep tone that’s not obnoxious. A solid racing-focused build that feels like it’ll hold up season after season.

Sofia Y. ★★★★★

Bolt-on install was straightforward, and the aluminum muffler sheds noticeable weight off the rear. First ride after fitting it, the throttle response felt crisper through the mid-range, and the tone is deep without being obnoxious on the trail.

Kevin ★★★★★

The stainless steel build feels rock solid, and the aluminum muffler shaved noticeable weight off the back end. Bolted it on in an afternoon, and the tone is exactly what I wanted—deep but not obnoxious. Forged for racing, and it shows.
