Yoshimura has used the World Superbike platform to develop the R-11 high-performance motorcycle silencer. The R-11 silencer has been developed with extreme use in mind, so inevitably they felt the best proving ground they could use would be the cut and thrust competition of World SBK!
The R-11 silencer features a newly-designed internal structure as well as an 'organically' shaped end-cap giving a truly aggressive style to your bike. It comes available in both road legal and race applications.
