I have a set of Krauser/BMW panniers for my 90/6, however be aware that by now original Krausers are getting hard to get in good condition, and the plastic is fragile due to time by now if they are. My own Krausers are more of a display item even though they are in good condition as they now feel too fragile for decent work.
As a consequence, I purchased Hepco & Becker pannier frames with rack to replace the ones on my 65 Mono, and frames/rack for my K75 so I can use the decent panniers that H & B make on either, as well as their top case that locks to the rack.
What I'm saying is, that the H & B panniers fit the stock BMW frames and vice versa, though some small mods may be needed. I'm not sure if they do the SWB R65's, but you can try that avenue.
