Not to answer your question, but to add even more choices, I ordered a set of Yacuga shocks fro Ted Porter's Beemer Shop for me 2001 1150GS. I have not received them yet, so I can't speak to them personally, but I can tell you that Ted convinced me they were the best choice for my bike based on the loads I'd be carrying (wife and luggage). He convinced me that they have superior strength (based on a larger diameter internal rod) and better responsiveness based on the use of a bladder instead of a solid diaphram (he can certainly explain better), and a longer life between rebuilds than the Ohlins (although maybe not than Wilbers). I assume they are also made for your bike.
I ordered the three way, with all adjustments. The price is at about the same as Ohlins.
You might give him a call and see what he says about your application. He also sells Wilbers and Ohlins, so I could have gotten any of them from him.
