Options are limited to non-existent.
There is a brand of soft luggage in the MandP catalogue that does a rack - very pricey though.
You could buy a set of pannier rails and panniers Hepco and Becker - not pretty. I have a set I never fitted to my tour but they look OK on the traveller I guess.
I use soft luggage and some of that non slip matting which protects the paint.
Otherwise you are down to getting someone to bespoke you one.
