Description
The Triumph TF450 is here and Yoshimura has our RS-12 Signature Series Full System ready to tackle the job of enhancing performance on this new 450 MX machine.
We enlisted a 304 stainless steel/aluminum/carbon fiber version of our RS-12 to provide more horsepower and torque to the TF 450 and man did it deliver!
Our RS-12 delivers a whopping 11.3% increase in horsepower @5000 rpm and a staggering 10.8% increase in torque @5000 rpm. Just where this new 450 wants more! Creating power - here at Yoshimura it's what we do.
The RS-12 is designed, developed and manufactured in Chino California.

2000 rpm (J2825)

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 TF450.
