Maybe I’m missing something simple, but how can I reduce the vibrations on my mirrors?
I’m having to use extenders, as without all I get is a view of my arm…
Maybe it’s the reason they’re so short in the first place, but the odd thing is, the one on the left isn’t too bad, but the right, above 40 mph means I get a blurry double image.
I’ve checked the bolts are nice and tight, am I missing something obvious?
its usually barends that help/cause mirror blurring so i guess with the extentions the weight of the barends isnt transfered as well to the mirrors.
Is there space to put an isolation washer or two? That might prevent some of the bar vibration affecting the mirror and has the advantage of being cheap as a first try.
The easiest way would be to change the weight of the mirrors and therefore the frequency of the vibration. A little difficult to do.
so is that easy or difficult? 
I was wondering if I could attach some weights to them and if that might help… not sure how I would though.
Nice big blob of blu tack perhaps?
Or new bar end weights?
Does the mirror open up anywhere? Maybe you could take off the back, fill the inside with something like blu-tack and stick the back on again.
Yes OEM bar ends are usually a specific weight to reduce vibration. Fitting after market ones can foul all of that up. I’d experiment with those first.
Bar, and therefore mirror, vibration has been on the forum before but I can’t remember under what title.
One suggestion that came up then was to fill the handlebars 1/3 to 1/2 full of dry sharp sand. Mention this to a couple of people when the subject came up in the pub and the well experienced enduro rider said he’d been balancing out vibes that way for years.
Someone else, (a physics teacher) explained how/why that works. I understood about half of the explanation. So we all had another pint.
Certainly a cheap answer.
It is all about harmonics and resonance so the solution is about changing the frequency of vibration which can easily be done two ways. One is to change the weight distribution, the other is to add things like spring washers.
I think that was the point the pragmatic motorcyclists glazed over. The scientific stuff was gone into in to a bit too much detail. At some point one of the group said “Forget all that, does it f*****g work?”
“Mostly, yes, but…” was the answer.
“Good. Then drink that.”
End.
In there, some where, maybe your answer Andy Cr15.
