Last night I tried some sound deadening material in a couple different spots to see what it would be to the vibrations i get through the pegs and bars. To my surprise this morning the pegs have almost no vibration and the bars were noticeably reduced. I put two strips on the neck in between the radiator mounts and one on each side close to the fender mounting point on the frame by the gas tank. I might try a couple more on the inside of the frame under the seat, but the noticeable difference has made the ride at hwy speed a lot more enjoyable for my feet and hands. Just thought I'd share my experiment and get feed back or questions
