I hit a pothole the other day at about 80, it was at a seam in the concrete, the front section had broken away about 4", but the back of the seam was flat. Still sore but did not go down. I had a shop check the bike and they could not find anything but the bike now has a vibration in the bars and pegs. Also at low RPM's it has a vibration and it gets finer and more the higher the rpm's go. Any advise is welcome, thanks guys.
