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.
