The BMW R 1250 GS is a beautiful adventure machine that claims 136HP and 105 ft. pounds of torque in stock form. We decided to add to the excitement of the 1250 boxer engine.

Using our Works Finish R-77 profile muffler we developed a slip-on that adds 1.4 % peak HP and 1.5% peak torque. These improvements not only make this beautiful BMW more fun to ride, our R-77 makes it rumble a bit more and adds a deeper tone when on the throttle. Did we mention we lost about 5 pounds, bring on the adventure!

Proudly made in the USA!

Yoshimura R-77 weight: 7.4 lbs VS Stock muffler weight: 12.1 lbs
