Topic: Tire Trivia - Or, what are These Wheels and Tires To?

[Dr. Frankenstein]

I picked up these wheels and tires as an extra when I got my '73 CB350Four(s), but they came as 'added value'; I'm just not sure WHAT bike or bikes they go to, and neither did the PO. Does anybody know what bikes they may fit?

I did write on a couple as to what bike(s) I think they might go to, but I'm not sure. Any ideas...? If you click on the pic you can get a closer look...

 Any fronts that are 18" or 36 spokes will be smaller bikes. The 4 bolt rotor hub might be a clue, I think 500,550,750 have 6 bolt holes.

I'd say the one in the last photo, the one on the far right, is from a CB360 twin.
I believe the late CB350 twins may have also used that hub.
I'd have to look at PN's.

The first one to the left with the chrome cap and black on the hub looks Suzuki to me;possibly came off a GS550 or 750.
