Yoshimura Slip-On R-11 (SSF)

Fits: 2017-2026 Suzuki GSXR1000

Derived from the R-11, the R-11Sq was designed to combine improved performance and noise reduction for Yoshimura racers competing in the All Japan Championship and the Suzuka 8 Hours. Its development drew heavily on Yoshimura's muffler expertise, resulting in a truly original shape. Proven on the Yoshimura GSXR1000 race bike, the R-11Sq is now available for street GSXR1000/R L7 riders.

A weight saving of approximately 34% (3.8 kg to 2.5 kg, titanium Cover) improves performance even in ways a power curve does not show. The sound is powerful while remaining legal with a rich bass at idle and a racy exhaust note that builds as you rev. Formed from a complex assembly of tapered shapes, the R-11Sq looks sharp from every angle and matches the race-derived GSXR1000/R perfectly. The Satin Finish Cover (SSF) applies a special surface treatment to stainless steel that is normally Mirror-polished, giving a satin texture with the look of titanium while retaining stainless durability.
