Front end vibration help

[WickedOne]

Haven't been able to find any threads about this so if it has been discussed please point me in the right direction.

I ride a 2005 CB900 Hornet and am experiencing quite a bit of vibration through the handlebars (feels like it is more in the right handlebar than the left) at around about 120-150kph. It gets to the point where my right hand gets "pins&needles" and distracts from my riding. Can anyone give me any advice on this?

I have wondered if it is something as simple as having my front wheel balanced or could it be something more involved? Would tweaking any of the front suspension settings (rebound damping etc.) help the situation?

Any advice would be great

[MSTRS:Me]

Thought about bar-end weights???

[WickedOne]

The bike comes with factory bar end weights, do you know if there would there be any diference with aftermarket weights?

Ok, has this developed recently or has it always been like this?

Normally not suspension if the bike is reasonably young.

Vibration through the bars can be caused by several things.
1. Out of balance front wheel.
2. Steering head bearings.
3. Brake disks warped and this is more noticeable when braking.
4. If it's only at certain rev ranges, can be motor vibration developing through excessive wear and again this is dependent on mileage covered.

Have only had the bike for a couple of months (from new) and it has been that way since I got it.
I may get the balancing checked on the front wheel and see if that solves it. Hope it isn't the head bearings (seeing that the bike is basically new and I have only done about 2000ks). breaking is smooth so shouldn't be the disks.
I have had Micron pipes fitted and I didn't notice a change when I had that done so yeah, hopefully just the balancing.

Thanks for the advice, if anyone else has experienced this any additional advice would be appreciated. (Especially other 900 Hornet owners)

Apart from a brief vibration period which occurs below 100k so I rarely notice it, there is no vibration worth mentioning. Unlike the vibration period on the BMW K100RS which occurred around 100kph and was a bloody nuisance.

It would seem that there is something wrong with the bike, have you discussed this with the dealer?

[WickedOne]

Haven't spoken to them yet, think that may be my next step.....

[Ixion]

Pins and needles ? Oh would that Phoebe would be content with pins and needles. It's when your hand vibrates completely off the bars that you need to be concerned. And when you can't keep your feet on the footpegs either.

Y'sure you're not just being over fussy? Vibration is pretty much part of the game on bikes (except the BMW K75 - absolutely zero at any speed)

[WickedOne]

I may indeed be a bit fussy, would like to get some feedback on the matter though as I am not sure if it is me being fussy or a prob with the bike......

I replaced my stock bar with a lower/flatter one the day after I got my 'net. I dont have any recollection of vibration problems, and certainly don't have any probs now. Whats more I dont have any weights/barends in the bars, but there is a MX style brace across the bar at the moment.

Because of other issues with the bar (bend is too far out to the ends of the bar) I will probably replace it soon anyway (maybe renthal or pro-taper next).

Sorry I couldnt help more. You could just get some aftermarket bars. Black bars are much nicer.

[WickedOne]

yeah, have been thinking of some aluminium bars as I have heard that they help, may be a good idea. - cheers!!!

I think that some of the Hornet 600 riders in the UK have complained of vibration throught the bars. There is an interweb site called 'Hornets Nest' that may be of use to you.

Most fours seem to have a bit of vibration.

Personally I'd check that your handlebar mounts were tight and then see if you can get a set of heavier bar weights.

I'll have a look at the site - cheers. May have a look for heavier weights as well.

if all else fails and you have only travelled this about of kms, after iys full service request that subframe be checked for alingment, surpise how many frames are out when assembled

The Hornet is know for vibrations in the handel bars, especially around 5,000 rpm, which would match the speeds you mention in top gear.

I have the same problem with mine and will be replacing the bars soon.
