Yoshimura Works R-77 Race Series Full Exhaust System

A unique offering from Yoshimura R&D of America. Works Finish is not a coating, but a special finish using Yoshimura’s special recipe of ingredients. The result is a stainless steel exhaust that after it goes through a heat cycle on the motorcycle, takes on unique coloring that looks much like those works components our factory racers use.

If you’re looking for that competitive edge, look no further than Yoshimura’s Race Series exhausts. These exhaust components are designed with nothing but power in mind. Each Race Series system is developed in accordance with noise compliance regulations imposed by most race sanctioning bodies worldwide.

Yoshimura created the R-77 full exhaust system to match the radical design of the modern motorcycle perfectly while at the same time removing heaps of weight, adding power and giving your bike a distinctive deep exhaust tone.

The R-77 muffler consists of a trapezoidal-shaped sleeve, maximizing muffler volume while offering a sharp silhouette to flow with the body. The innovative end cap is reminiscent of the Yoshimura R-55 exhaust system, featuring sharp edges for an attractive, eye catching appeal.
