My bike is two months old. After about 1000 km's. I noticed rubbing on front disks. I think the left one making all sound. And the worse, this rubbing shaking handlebar after about 95 kmph and all vehicle after about 120 kmph. It is not a constant rubbing. It is only rubbing at a point of a spin of wheel. So first, I thought my disks are warped. But two disks and pads are changed. And it's still rubbing. Only shakes and sounds a bit less than before. May be %30 less. So the situation is very very strange. If I don't use the bike 1-2 days, I can't hear the sound clearly before first front braking. Then annoying thing is back... We lifted front wheel and while turning it it is rubbing at a point of every spin.
It makes it difficult to solve the problem of having rubbing not constant but with intervals
I think my service can't detect the cause of problem and I want to suggest them something to look at. Can calipers cause this? Do you have any ideas?
