Yoshimura has been working tirelessly on the development of the RS-9T (Tapered) Exhaust with American Honda HRC's engineers to achieve maximum performance and mass centralization, to optimize rider usability. Yoshimura achieved their goal by moving the RS-9T mufflers forward and relocating them under the side number plates. Working with Honda R&D in Japan and the HRC Japan MX Race Team, Yoshimura was able to deliver an exhaust that provides more tractable power with improved torque which in turn leads to better handling and performance.
