Yoshimura Race RS-12 Suzuki DR-Z4 S/SM (2025) Stainless Full Exhaust System

After an impressive run of over two decades, 2025 brings an all-new Suzuki DR-Z4S/SM.

The new 398cc single-cylinder water-cooled engine is now fuel-injected! We developed our RS-12 Race Series full system exhaust to enhance every aspect of the new DR-Z, and the response was just what the doctor ordered. The RS-12 Race Series Full System packed substantial gains in performance, adding 5.5% in hp @6,640rpm and a 2.8% increase in torque @5,180rpm. These gains were made with our included/installed USFS spark arrestor SA-21-K! A custom stainless Yoshimura heat shield is included.

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