wheel swaps for a kz550 ltd?

I want to change out my stock 19" and 16" alloy wheels on my 1980 kz550 ltd for 17" spokes, front and rear, or something close.
What model Kawi wheels should I be searching for that would be the cleanest/easiest swap?
1979 kz400?

I was hoping for rear disc brakes and dual discs on the front, but I would settle for rear drum like my current setup.

Thanks for any help guys,
JC

The 1979 KZ400-B2 uses 18" wheels front and rear. The 1979 KZ400-H1 uses 19" front and 16" rear. I am not aware of any KZ model that uses 17" wheels. Ed

Ah, ok.

18" could work. I'm mainly just trying to avoid the massive 19" on the front. I eventually want to get dual sport style tires for the bike, and not many 19" dual sport tires exist.

So would the 18's from a kz400-B2 be a large enough/strong enough wheel for use on a kz550?

really trying for something like this:
