I would love to hear an answer to his question. Sad truth is haven't heard of cheap rim options, Mr Blitz 2005 gs rims will fit for your fatties.
Tubed rims from what I understand have a different bead lock to tubeless - this is why when I get around to it, will seal the spoke nipples, tape the rim but use slime in the tube. This is so I won't get stuck and can get home.
It is a dam shame all the K models have the shaft on the wrong side, otherwise there would be a ton of options.

I came across a Ducati adapter???? The bloke had the duk wheels on his beemer. Looked superb, when I went looking with heart a racing could not find one for all attempts. Me thinkus they may have been only built for a one time customer. But dam the would sell thousands.

Whew, you have been diverted. The biggest issue for tubes is the inside of the tyre. Found this out on my Ducati classic,some tyres have ridges inside the case and on tubeless not an issue but they are hell for a tube.
Tube really only come as heavy duty or standard, this needs no explanation and the HD’s are marginally heavier.
