Yoshimura Suzuki GSX-8R / GSX-8S AT2 Speed Series Full System
The Suzuki 800 twin platform delivers impressive performance for a parallel twin, and Yoshimura unlocks even more potential with the AT2 Speed Series Full System for the GSX-8R and GSX-8S. Developed over months of engineering and dyno testing, this 49-state friendly exhaust system enhances both power and sound while reducing overall weight.
Featuring Yoshimura’s signature AT2 Speed Series Works Finish, this full system includes a carbon fiber heel guard and is engineered to maximize the performance of Suzuki’s 776cc, 270-degree twin engine.
