I have a chance to get some mag wheels from a 75' CR750. Does any one know if these rims will fit on my 78 CB750f? The race wheels have dual front rotors and the rear is a single rotor. same set up as my bike but will there be problems with spacing. I think the front is a 18" and rear is a 17".
If this doesn't work out what would be my best bet for a larger tire in the rear. I'd like to have a wider footprint. Would a 16" gl1000 wheel fit if so what years?
I'm sure some of these questions have been answered somewhere, but I suck at the internet.

Any help would be much appreciated.
Peace.
