I didn't notice too much vibration, but if you want ideas, the guys in the OZ section had a good camera mount. He has an S*R and mounted the cam on the radiator cap. Was vibrating like crazy but he found a way to stabilize it.
I don't think the camera was vibrating so much as when the bike was revving high it was almost like interference with the recording, the sound and video was effected. It was only for a short time during one of the recorded sessions.
