What can I do to stop the front of my 2012 dyna street bob from shaking all over the road at high speeds? Just up around 90-100mph it will shake and wobble like crazy. I have a friendly wager tomorrow with a gxsr 600 street bike in the quarter mile and in the half mile with a friend of mine who talks way to much about his Japanese plastic toilet paper roll like it's gonna blow me away. I don't think he can do it but I have no idea. I do know that I have never been over 100mph on my Harley because it shakes way to much and makes me nervous. Specially since I don't own a helmet.
