Happened to me today, I was riding 70 kms P/h and I held up my hands, and the bar started to vibrate.
The Tyres are not new, but they are not damaged, or slick. The tyre pressure is normal.
Any one experienced this?
-
First, have another good look at your tyres (front especially), they may not have damage at first look, but might be suffering from 'cupping', or other issues
-
They seem OK to me.
A bit used but I don't think it's enough to have this behavior.
-
What tyres do you have?
I had issues on my 2013 Glee until I had Anakee 3s fitted. Other tyres may be better but the stock tyres were horrid.

bridgestone trail wing 101

When you say the bars vibrated, I take it you mean "Shake" the bars are going back and forth and shaking? Then 99 times out of a 100 it's wheel balance! you say their not damaged or on the limit, But Gassoon has raised a valid point if they are cupped or have worn in a certain way they will be out of balance, just like the OE Bridgestone front I've just changed on my Wee at 5,000 miles, it could have went to probably 7,000 miles but I don't tolerate a front out of balance and changed it.
You have three options, Replace it, Live with it, Or remove the wheel and have it Balanced.......the choice is yours!!!!... :thumb:

I'm not sure if the wheel is unbalanced, or the tyre is damaged.
Going faster I don't feel the shake that much, the shaking is less pronounced, has it's slowing down, the shaking becomes stronger and more pronounced. If it's unbalanced the same shaking should occur at high speeds with the same intensity or worst.
It could be the tyre, I'm not questioning that, and I do believe is what makes more sense.
But also wonder if it could be something wrong the the direction bar, rim, suspension ....

Not unheard of no matter what the bike. If the shake/shimmy is there from fitting a new tyre then a refit and balance can usually sort it, but if it occurs midlife in a set of tyres it is usually due to wear of some sort. However it might not always be the front wheel that is the culprit. I once had a GL1800 and when the back tyre squared off sufficiently the steering used to shimmy when I took my hands off the bars. So it was the rear tyre that was causing it. How do I know ? The front tyre was fine on the first occasion that I noticed the shimmy but the rear was shot, so I just replaced the rear on that occasion and the shimmy was gone !
As is suggested above unless there are any other undesirable handling issues I would live with it until it is time to replace the tyres. After all, 99% of the time Your hands will be on the bars :grin:
-
unfortunately can't change the Tyres now. Where I live we don't have highways, just a speedway and lots and lots of curves. So my Tyres are not square.
I will look for Tyres, and maybe next month I can change it.
-
A rear wheel imbalance usually causes vibes through the whole bike and only shows at higher speeeds, This is classic front wheel imbalance, I've seen this question on so many forums over the years and the answer is re-balance or replace! A good few years ago I owned a Honda Blackbird and run Avon storm tyres as favoured by lot's of owners at the time, and the front scalloped quite badly and went out of balance half way through it's life, and as I fit and balance my own tyres I re-balanced it and was OK to the end of it's life!
-
Hmmm, thanks for all the advices.
I will balance the tyre, is cheaper than changing the Tyres ehehe.
Thanks ... I will let you know the outcome.

Don't always assume the tyres are the issue: I get headshake on the KTM when I fit the top box - cost me a new front tyre that I didn't need before I sussed it out. Same on the Spada - something aerodynamic causing the issue, not tyre.
-
I have just replaced my annakee 2 tyres for avon storm 3d xm full road tyre a lot quieter but a bit twitchy at the back bounces round a bit
-
Check the bolts holding the bars haven't worked loose.

+1 on this suggestion. Top boxes especially when heavily loaded, do not agree with some bikes.

I had a similar problem on an old motorcycle. When I released the handlebars in deceleration phase, it was going quickly from right to left (between 70 and 90 km / h only). There was a flat on the front tyre. Replaced the tyre, problem solved. Check yours by putting your hand all around the tyre on the center band.
-
Could be uneven tyre wear or maybe a loose fork yoke. Check the fork yoke bolts and also the wheel spindle bolts.
-
there is a free play in the steering stem .
-
one of the balancer could be missing .
-
The ocilating effect could be the front wheel out of alignment, which is a pretty easy fix.
Also check both forks are set up the same and front brakes are working properly.
An out of balance front wheel usually causes vibration at a certain speed then stops as you accelerate.

Lots of bikes do this. Some badly and some much less so and some don't do it at all. I recall some years ago some research was done to try and find out the cause and many of the suggestions already suggested here were investigated but the only thing that was found to have any real influence was the front/rear weight distribution and where it was attached. The less weight on the front end made the whole thing more likely to occur and the more rear weight and the further back it was put, the worse it got. Obviously any issues with stuff like tyres, head and wheel bearings, wheel alignment are only likely to make matters worse. It generally now thought to be a rather complex function of frame geometry and centre of gravity. If I take my hands off the bars on my Vee at about 25mph it will oscillate very slightly but stops the instant it put a hand on either grip. A friend has a big Yamaha and that wiggles quite unpleasantly even with both hands on the bars. Removal of one's hands and it would go into a real tank slapper! Everything has been checked and replaced as needed and nothing has made it any better. It's just the way some bikes are.

Or 'Don't worry - they (mostly) all do that, sir' lol
Er, sorry hookie , couldn't resist :dance:

My bike yesterday went to the dealer for maintenance.
I asked them to check it out, the first thing he says was if I already tried without the top box, has suggested here.
I said, no because I have it for so long and never happened this. The dealer says that sometimes it takes a while to happen, as the tyre rubber is burning.
After I while they call me back and said that my front tyre is in V shape. It's wasted on the sides, but OK in the middle that this could be the answer for the vibration. Not sure if this could be the why, I already had sports bike and the sides got wasted and the middle OK but the steering never vibrate.
But it's a valid point of view, I never had this kind of bike, and this kind of Tyres, so not sure what to expect. I will try ridding without the top case first, if it continues soon has I can I will try with new Tyres.

Or "It's a feature, not a fault sir". As a mate who has a Ducati with it's air cooled clutch that you can hear rattling 100 yards away says to me ...
