The new 2023-24 Suzuki 800 twin platform packs quite a punch for a parallel twin! Yoshimura brings you the uncompromising power of our Speed Series 49 state friendly system for the new GSX-8R/S.
Our engineers knocked it out of the park on this one! The product of months or development, an AT2 Speed Series Works Finish full system with a carbon fiber heel guard and packed with some impressive new power for the new 776cc, 270-degree engine… the results are astounding!

The new Suzuki system comes to life on the dyno adding a Max HP of 5.7% paired with a torque gain of 6.1 percent. As if all the new power wasn’t enough, the new Speed Series system even manages to trim a whopping 6.5lbs of weight over the stock unit. There's no mistaking the signature Yoshimura sound and a GSX-8S/R equipped with this new 49-state friendly system delivers a sonic tone that does not disappoint!

Also available as an option for this full system is our Low Volume Insert INS-20-K and our Aluminum Muffler bracket kit 200BG117200.

Yoshimura's AT2 is proudly designed, developed and manufactured in Chino, California.
