Yoshimura R-11 Cyclone Full Exhaust – EXPORT SPEC (GSX-8R & GSX-8S)

A name forged in racing heritage.
The Yoshimura R-11 Cyclone delivers a deeper connection between rider and machine—amplifying the character of Suzuki’s 270-degree twin with a tone that invites you to keep the throttle open.

Product Overview

Developed using Yoshimura’s racing expertise, the R-11 Cyclone is engineered to enhance performance across the entire rev range—from everyday riding through to high-rpm sport use.

The machine-bent exhaust layout optimises flow efficiency, while the R-11 silencer sharpens both sound and response. The result is a system that feels alive beneath you—controlled, responsive, and unmistakably Yoshimura.
