I've just collected all the parts to add an 'S' style fairing to my monoshock R65. Here in the US I ordered the kit from Bob's BMW as well as the fairing. I did not have the original headlight, so had to source headlight ears and a headlight from a BMW breaker. He has tons of parts, you can find him on Ebay as larry chiraba.
I have not yet gotten the parts painted, I'm going to have the pin stripes on my tank redone at the same time. Once that's done, for my build, the steering bearing will have to come off to get the headlight ears on, so i'm taking it to a professional for that work. Larry and I live at opposite ends of the same town, he speculates that my R65 has K100 bars on it already.
There are some other fairing options out there, but not very many.
