I want some easy clean wheels for my every day ride 1981 R100, These 3 spoke wheels look ideal.

Does anyone know what is needed to fit these - I have a mono swinging arm - is that a K diff? - does the driveshaft fit ok?
Wheel offset? etc etc

Your bike is an '81? Not a '91? Is the mono swingarm on your bike now, or are you intending to put it on? The latter is not minor surgery. Seems like a lot of work to ease wheel cleaning.

"The latter is not minor surgery" - Other than welding on a suspension mount and bolting up a Mono subframe - what else is there to be done?

I can see now that it is a Mono final drive with it's flange cut back so that sorts out the drive shaft and apparently the 3 spoke wheel and disc bolt on - what is the caliper bracket mounted too?

If you're handy with a welder, all things are possible, but a better spray-on wheel cleaner, a good brush to reach into the crannies of your '81's rear snowflake, and maybe a set of rear disc pads that generate less dust would seem more cost-effective. Your way, you'll have roached the value of the bike to most potential future owners who'll likely have more confidence in Berlin's workmanship than in any DIY PO's re-engineering. But, hey, knock yourself out.

Oh sorry khittner - I didn't realise that this was a restoration Forum.

No apology needed. I thought you wanted easily-cleaned wheels---you really want clean-sheet-of-paper wheels.

From Phil Hawksleys website, a highly modified R75/5. I think the wheels are from a Yamaha:
