Howdy, I hear some guys say that the WRs are stable and don't headshake and therfore don't need a streering dampner. My reason for shopping for one is I ride eastern style, rocky, tree root, tight trail. I thought the dampner might take that jolt out of sharp impacts. Am I mis-informed? I am considering several mods for rough terrain riding and to dampner was going to be first, but I'd welcome your opinions. New bike is an 07 WR 450. Thanks.
