SUZUKI DR-Z4S / SM - (2025-2026) Yoshimura Stainless Slip on RS-12 Silencer - Works Edition, Matt Carbon End Ca, stainless heat shield - alternate INS-32-K low volume inser

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! Yoshimura developed their 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 2.8% increase of torque @5,180rpm. These gains were made with the included/installed spark arrestor SA-21-K!

If a Race Series full system is not what you're looking for, Yoshimura developed the RS-12 slip-on to pack performance on the DR-Z4S. The RS-12 Enduro Series slip-on provides great performance; 4.1% hp boost @8,000rpm and 2% increase of torque @4,800rpm, with the spark arrestor installed. The RS-12 slip-on developed for the Suzuki DR-Z4S/SM hits it out of the park!
