I have an annoying vibration through the handlebars on a FHTK. It occurs between 25mph through to about 40mph. It is a high frequency buzzing feeling as opposed to a low frequency thump, thump type of vibe. I thought it was the wheel bearings, took it to the dealers, they said it was not the bearings but possibly due to an out of round tyre (which was new). I checked the tyre with a dial gauge, it is only 0.020” out of round, so doubt if that is it. Convinced myself it was the front wheel bearings, I changed those, no difference the buzz is still there.
It is road speed related, no matter what gear or pulling the clutch, it is there at the speed range stated above
Anyone got any ideas please.
