Noticed this today when sat in traffic, not just making a buzzing noise but causing the bars to vibrate....
As soon as I let off the brake lever it stops ....
Anyone had this?
Also got a fairly bad front end wobble at 110+mph (on track) that I have been trying to diagnose so I know the discs calipers etc are all tight, this is probably down to the 10k miles I have put on the pr3 tyres, mostly motorway so a bit squared off. Shame as there is loads of tread left. It's only Google telling me this, I'm no expert
Cheers.
