The rubber in your first picture looks like the front tank supports on my
Honda CB200. (see the detail of the tank)
I've never seen anything like it on our R65s.
The front tank rubber support on our bikes is one-piece that slips over a long, half-round steel bracket.
Your question about the hole above the key.
That is a blank for the 4-way flasher factory accessory.

I think I still have the one I removed from my panel. Â You can have it, if I haven't already given it away!
