The race bred R-11Sq from Japan is here for the current gen Suzuki GSX-R! They go together like peanut butter and jelly.

The R-11Sq is used by the Yoshimura Suzuki World Championship Endurance Team (SERT) and has been refined in the crucible of Endurance racing. This profile is iconic for Yoshimura and just bleeds cool factor.

Available in two finishes, a satin stainless steel and a beautiful blued titanium sleeve, both options incorporate the beautiful R-11Sq carbon fiber end cap.

The performance and sound of the R-11Sq is like no other. This slip-on removes up to 1.9 lbs. of weight from the GSX-R 1000, and add up to 3.8% more HP @9,200rpm and 4% more torque @9,400rpm

Yoshimura's R-11Sq is designed, developed and manufactured in Japan.

Nicholas C. ★★★★★

The titanium blue sleeve gives the bike a sharp, aggressive look, and the sound is deep but not obnoxious. Installation took about 20 minutes with basic tools, no alignment issues.

Victoria ★★★★★

The fit on the GSX-R is spot on, and the sound deepens nicely as you get into higher revs. I can feel a slight bump in throttle response, especially coming out of corners.

Robert M. ★★★★★

The titanium blue sleeve looks even better in person, and the weld quality on the stainless body is flawless. After a quick test ride, the tone is deep and throaty without being overwhelming at cruising speeds—exactly what I wanted for my GSX-R.
