It would seem that I have a high speed 70 mph high, frequency vibration in my 2004 R1150 RT-P with 120,000 miles on it. The tires are new and I have micro beads for balancing which I have used before with on problems, the rims are also good.

I replaced the front wheel bearings as I thought that was the problem. as it seemed to only be felt from the handle bars, but with that replaced it does seem to be the rear where it is.

I now think that it could be the bearings in the final drive starting to go any one else have any ideas on this? drive shaft, splines, ETC.
