Yoshimura RS-9 Exhaust for the Honda Grom / MSX125 to improve performance and and safety



The Honda Grom's 125cc engine is quite fulfilling, however it is still restricted. Yoshimura's RS-9 will help reduce weight and restriction and improve throttle response. A common problem we have while navigating the city streets on our smaller bikes and scooters is we go by unnoticed and it can become dangerous. With the a less restricted muffler from Yoshimura, on top of increasing the throttle response, you'll also get the increased volume while still keeping 'noise' to a minimum. The Yoshimura RS-9 full exhaust system comes with all the equipment to bolt right on. The muffler features stainless steel piping and is dressed with a carbon fiber sleeve and a riveted CNC machined mounting bracket in Yoshimura-red. The muffler includes a matching carbon fiber end-cap / tip.
