Suzuki DR-Z 400 S/SM have been a staple of the street and super moto enthusiast for quite a long time. The RS-2 equipped with updated muffler branding and installed spark arrester, delivers all the power you’d expect from Yoshimura. Our dyno indicated a 4.2% increase in max HP and 9% max torque, it’s no wonder this is the go to system for the popular DR-Z.
