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.

Our now-iconic RS-12 Signature Series full system not only looks stunning on the TF250X 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 Yoshimuras latest exhaust system for the Triumph TF250X.

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