Simple to install and a direct replacement. The trapezoidal muffler with a dual outlet carbon fibre end-cap is up to 3db quieter than the standard R77 (without the insert fitted). It dramatically improves your bike's visual appearance.
Produces more power, more torque and saves weight. All parts required for fitment are included (brackets/fittings/link pipe etc.) with full fitting instructions. Developed to fit without fuel modification, and to give the unique Yoshimura racing sound.
