Hey all, has anyone found a nasty vibration sets in above 3000rpm and 4500rpm on the 900.
My 2200km old bike seems to be developing this bad vibe mostly thru the handlebars which in a very short time is making my hands numb....... Is it just me or my bike or are they all a little vibey ?????

they are all a little vibey, but it should not be enough to make your hands numb in a short period of time

try loosening your grip on the bars a little you really only need to rest the hands on

[dandywarhol]

Do you have standard 'bars on it?
The vibration dampers at the end of the originals do a good job................

Different bars or bar-end weights may help. I still have standard bars, but in an early effort against turbulence I picked up a couple of stainless steel TRX 850 ends which are heavier than the 900 stock ones and seemed to help, so you may like to consider that. They are each about 1cm longer than stock, though, which I don't mind, but some may object to the "wrangler" look

hey Pict does yer 900 have hazard warning lights ?? or is that the long switch on the LHS bar cluster ??

[Pict]

Yuss, it's the hazard (all 4 indicators) light switch - standard on 900s

[Bratski]

If it has suddenly become apparent, check engine mountings, wheel balance and so on, but if it's always done it, then you should be able to tune it out by altering the bar end weights like Pict says. Mine is a bit vibey, but certainly not hand numbingly so..... good luck

Thanks mate, will give it a try

Thought about that too, has anyone heard of "Hunter Flat Bars" apparently they can reduce the vvibes by up to 70%..............

Yep its all stock......... maybe im just a woose ????

Have tried that too.... even bought new gloves too see if that helped, i am looking at a product called Hunter Flat Bars , has anyone heard of them???? Or maybe a set of foam grips

Not heard of them, but they sound interesting - pricey, though. Web site is well done and they're clearly confident of fitting almost any bike, inc. TDM850 (being US-based they haven't heard of 900's)

As your bike is so new, this is the most likely time for a production problem to show up (something not tightened properly), have you had the first service done? With a bike this new I would defiantly go back to the dealer to get it checked out before trying new bits.

Good point and i agree its worth getting the dealer to take a look..thanks

Being a twin, the TDM has vibes. So had the GS. But both are not buzzy, they don't numb your hands. If my TDM would have a hand numbing buzz I'd suspect something not enitrely correct (thinking about valves or something like that). That, or you're not used to any motorcycle... and/or are a wuss

Aye - 'e mannie kin be a bittie coorse at times.

I'll be interested to see what results you get from the flat-bars.

I'm having some vibration/grip issues with my right hand lately (it's me, not the bike) I've always preferred thin grips, but I've just fitted foam grips hoping the thicker grips might help with my right thumb tingles (happens on both bikes). I've also filled the bars with expanding foam to help calm the slight buzz (couldn't find the silicon when I went looking).

Now why do Yamaha have those holes in the bars under the kill-switch/starter button. Those who are awake might have realised that the expanding foam expanded through the holes in the handlebars into the switchblock. I've chipped away 98% of the foam inside the switch, the killswitch is working properly now but the starter button will need to be disassembled to clean the contacts(it works, but only if pushed very hard). That's tomorrows job.

Has it improved the vibes? Don't know, I wont be riding it till the button works properly.

Strong words from a fellow 900 owner

well i pumped silicone into my stock handlebars when i replaced them a few years back and it stopped the index piggy on me right hand from going numb !!!

I’m glad I’m not the only one experiencing problems vibes. I knew moving from an inline 4 to a twin would result in vibes but it began to piss me off the other week when a went on my first long run on the TDM900.

After about an hour of 60mph riding the vibes through the bars really started getting to my hands causing a numbing sensation. So a stop and a ciggie was in order only to find that once back on the bike my hands were crying out for more frequent stop to get some feeling back in them.

I’m on a 900 with standard bars, Suzuki DL650 handguards with the standard bar ends drilled to make them fit. And run on Carbon Can Co exhausts.
The bike has done 1300 miles and apart from its 1st 500mile inspection hasn’t been in for a service yet.

Any ideas on reducing these vibes as I love the TDM and bought it with the intention of touring but wont get too far too quickly till I can dampen these vibes down.

So any news on whether this worked for you?

Wicky – what sort of silicone did you use? And is there any other advice you would offer.

[Pict]

Not having a vibes problem, but I did fit heavier S/S bar ends (Oberon, marked for a TRX) early on, so maybe they helped?
