    Cant say there are that many vibes in a LC8 - but if you think you need them get foam grips or maybe investigate the bar bend itself. Changing to a MX or SX bar will make a world of difference!!!:deal

    FWIW, I thought the Vibranators made a large reduction in the felt vibrations.

    Why not just order a set from them?

    I've wondered about filling the bars with lead shot, or something similar. Probably with a bit of silicone to hold it on. Never got round to trying it though :(

    They are heavy enough to pick up as it is!!!

    I know what you mean about vibrations, feel the bar clamp at speed and it has some big vibes on it. Thats with balanced 17/19" wheels too.

    I am going to try filling the bars with silicon.

    Don't bother adding these, despite being quite heavy (about 180g), they make no difference at all!

    BMWs always have them, but why?

    Cyril's bike used bar-end weights and the KTM isolated handle-bar mounts.

    Short answer: They look interesting. Try them out and report back to us.

    Long answer:
    The thing to remember about your vibration issues is that they are YOUR vibration issues. Unless there is something mechanically wrong with your bike, you can't really make them go away. You can only change how they affect you.

    Think of your bike, bars and YOU as a system. Vibrations start in the engine and wheels, transmit through the frame, triple clamps, bar mounts, bars, grips, into your palms, through your wrist and up your arm. Change any one part of that system and you change the whole. The change may be major or may be so minor that you can't detect it. You could even make it worse. The only way for you to know what works for you is to try it. I suggest you try the free stuff first.

    1) Is the bike mechanically sound? Sorry, had to be asked.
    2) Riding position. Are you putting too much weight on the bars or gripping too tightly? What angle are your wrists? Does changing riding position alleviate vibration problems? If so, try to figure out why.
    3) Ride in a different gear. See what changes.
    4) Bar position. Rotate the bars a few degrees either way and move them forward and back if you have adjustable mounts. Pay attention to how bar position affects riding position and wrist angle. Experiment. Note that if you move the mounts one way and then rotate the bars the other way, you can have the grips in the same position, but they will be at a slightly different angle (This is what worked for me in the end - it vibrates as much as ever, it just doesn't bother me any more. And it was free.). Try short risers. Better or worse?
    5) Bar weights. Mostly they just change the resonant frequency of the bar system. It may be enough to help. Take the ones you have off. How's that? For the most part, even fancy bar weights are still just bar weights, the important thing is mass and distance from centre. The vibranator seems different, though. It looks like it would respond in a unique way. I'm intrigued.
    6) Change the bars. Even an identical bend from a different manufacturer will transmit vibrations differently. The result would be similar to adding or removing bar weights. More better would be to change the bend. NOW we're talking. Liked the risers? Get a taller bend and throw them away. Found a bar position that you liked but it was weird for your wrists? Pick a bend to fix that. Sit on the bike and hold your hands out where you feel that bars should be. Look at all the angles.

    Sorry for being long winded, but that should give you some ideas before you spend a lot of money on stuff that ends up not working.

    Good luck!

    Interseting that he has his light switch set up to operate dip/main with his thumb. I prefer to rotate the top part of the switch 180 degrees and operate the kill and horn with my thumb....

    So I filled my bars with silicon bathroom sealer last night. Took a fair bit of force to push the stuff from one side all the way through till it came out the other side.

    Then I dug out enough length for the handguard inserts.

    This morning I realised the bars have locating holes drilled in them for the switchgear!!!!!!!!

    Fortunately the silicon had not fully cured so I was able to peel/dig it out the switches!

    Will ride the bike at the weekend to see if the vibes are reduced......

    He also seems to be using foam grips.

    Vibranators go on the handlebars?

    All this time my girlfriend had it all wrong.

    Just got back from a 140 mile ride with silicon sealer in the bars. All asphalt, cross country roads and about 12 miles of motorway at a constant 80 mph.

    No numbness, no need to bash my hand onto my knee to wake it up.

    Definately reccomend giving it a try. Costs next to nothing.

    Thanks to you all, the bar weights seem a good idea but I am not going to cut the end's of my bars off! I don't mind the one's that stick out pass the hand guards, but what ones and who off, as I don't want to order the wrong ones, at the moment I am thinking I shell try the silicon implant! but I really would appreciate if some could be more pacific to the bar weights I will need for my 2012 ADV with out chopping up my bike!

    Thanks and cheers Adss.

    I went through the numb hands issue last year. First on an old Suzuki Bandit1200 then brought a Triumph Tiger 800 that was even worse:huh

    So, I know how frustrating it is to have numb hands and even numb up to mid forearm. Potential for long term damage as well.

    However, I've currently got two 990's on the road and neither have more than the low frequency vibe you're going to get with most big twins. BMW or Ducati for instance. Rode both and not a lot different.

    Could be the bike. Can't discount it but might be worth finding another to swap ride and compare notes.
