Yoshimura RS-9T Signature Series Slip-On Exhaust

Yoshimura has been working tirelessly on development with American Honda HRC’s engineers to achieve maximum performance and mass centralization, to optimize rider usability. Yoshimura achieved all this by moving the new RS-9T mufflers forward in order to tuck in under the side number plates. Working with HRC race engineers and the 449cc Unicam Honda engine and its unique downdraft fuel injection system, Yoshimura was able to deliver an exhaust that provides more tractable power and improved torque.
