    Hi all.

    Is there any thing I can do to help the vibration in the bars at high speed, At say 70 80mph and above? But I do not ride that fast OK.
    Thank You. :)

    I get the same on my Breva 1100 but only on the throttle hand. I think I have too much weight on my hands because if I have a very light grip on the throttle I can reduce the effect of the vibes considerably.

    Somewhere else I noted that throttle balance could also cause the vibes.

    It seems to me that the weights could amplify the vibes unless isolated (this is similar in tuning an archery bow for competition). Isolating the weight would lead to the reflected vibrations being anti-phase. Will give this a little more thought before trying for myself.

    Steve.

    TB balance is important.
    You did not say which V11. DO you have clip-ons or handlebars?
    Different grips, adding or removing weight from the end of the bars (it is, as mentioned a tuning thing and not always a "more is better" deal), or filling the bars with lead shot, are all things that can help. I am sure there are others options as well.
    The biggest thing to me, though, is the TB (throttlebody) balance.
    The wifes V11 becomes almost electric motor smooth around 5K.
