I rode a R100RS for many years, then a R100 set up like a "S", and I still have a GSPD, which I ride regularly. As good as they are, I never really bonded with any of the post airhead beemer boxers, and I also tried many other bikes, unsucessfully looking for a replacement, until I found my V11 LeMans, eight years ago. No BMW boxer, of any vintage, is as fun to ride as a V11. For me, it just never gets old. In stock form, the airheads are more comfortable than a V11, but V11 ergonomics are easily modified, and mine is now very comfy for solo sport touring. Unfortunately, there is not much you can do for the passenger. The pillion position is what it is. If you've been doing your own airhead maintenance, you won't have a problem adapting to V11 maintenance.
