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 TF450 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.
