The R-77 consists of a trapezoidal-shaped sleeve, maximizing muffler volume, while offering a sharp silhouette to compliment the bike's styling. The innovative Carbon Fiber end-cap is reminiscent of the R-55, featuring sharp edges for an attractive, eye catching appeal. Featuring Yoshimura's innovative duplex headers, these headers offer superior mid-range performance with smooth torque and power curves for optimal gains. This Full System also offers considerable weight reductions by eliminating the stock under belly muffler.
