Description

One of our favorite small bore bikes, the Honda Grom has a new offering from us here at Yoshimura - our RS-9T Speed Series High Mount!

We've had so many requests for a high mount for the latest gen Honda Grom, we just couldn't resist. This new Speed Series High Mount system, like our low mount, has power optimized to perfection. The header includes an 18mm Wide Band O2 sensor bung to allow for the perfect tune. The RS-9T muffler with matte carbon fiber end cap and heat shield is tucked in tight to the chassis to help minimize crash damage.

When it comes to performance Yoshimura is squeezing every drop from the 124cc small bore Grom engine. Up to 10.9% more HP @8200 rpm and up to 7.4% torque @6600 rpm. Our Integrated Sonic Chamber allows us to boosts power over the stock unit and gives the Grom a little extra bark all while keeping the new Speed Series full system 49 state friendly.

Yoshimura's RS-9T is proudly designed, developed and manufactured in Chino, California.
