rims

[BIG BEAR]

I have a 1981 cb750c and I was wondering if you can put on new rims.  Either after market or newer honda or yamaha.  I would like to keep the rear drum break and the front disc.  Please let me know.

Well I am of the mind that the K rims for your year would fit but I do not know. Maybe check if lukem knows or woodsrider250, someone else may chime in too.
I guess it depends if you want to keep the mags style or go to spokes. I know the K rim is a spoke with drum brake.
You can get a new rim here if you want http://www.buchananspokes.net/ but you still need a hub.
