I have picked up that several on this board do or have done some motorcycle touring. I'm wondering what you do to isolate your cameras from the high frequency vibration of the machine? Many years ago I had mysterious problems with base plate screws that would not stay put in my Nikons. Finally traced the likely cause to the vibration being transmitted through the bare metal floorboards of my VW. Started keeping the camera bag on the passenger side seat and the screws quit falling out so much. So what's a comparable fix for the two-wheeler?
