      May be an inherent problem of the forks....?

      I've had a few experiences with front end wobble on my 80G.
      All had been at 70/80+ mph and where induced when running over a "bad" piece of pavement. On a smooth road have never had a problem, even at 100+.

      Hot rod XS having beefier suspension front and back and dual fork braces has not experienced the wobble yet.

        Hi Guys,

        The road-race crash linked to earlier was caused by a rear wheel collapsing; Circuit weight parts on a public-roads circuit (Isle of Man TT race!)

            Kawasaki had a lot of lawsuits on thier police bikes, a couple decades ago, for the high speed wobble issue.

            A true high-speed wobble, however, isn't caused by road irregularities, or worn tires, and the best way out of a true high-speed wobble, strangely enough is to accelerate!

            Don't worry, it takes nerves of steel to accelerate more, when your bike is dancing in the lane!

            I've had nearly every bike I've ever owned to redline (and beyond) in high gear on more than one occassion and (knock on wood) have yet to run into this phenomenon.
            Nice day, if it doesn't rain...

              Have been fortunate to have never experienced this. But a question, does anyone think that a steering damper might help or stop the situation?

              Once you un-can a can of worms, the only way to re-can them is with a bigger can.

                It would mask the situation. Whatever is causing the wobbles is still there.
