The original go-to for the Hayabusa, polished R-77's with carbon fiber end caps, attached to our exclusive Works Finish tailpipes.

Of course there are performance advantages too! The R-77 dual mufflers reduce as much weight as 11.2 pounds! Horsepower and torque are up, and the exhaust note of the dual Yoshimura R-77's is a classic as the Hayabusa name!

Our R-77 slip-ons and Onyx Edition is proudly developed, designed and made in the USA.
