Nice! Those are one of my favorite BMs. A bit lighter and simpler than most, good bikes.
Uh, not really lighter than many.
I had a 1996 R1100RSa for about 40k miles back in the mid-90s.
As a matter of fact, I had it alonside my 1996 FLHRI Road King.
If memory serves the BMW was about 600 lbs and the Road King was 700 lbs and ironically the BMW actually FELT HEAVIER (because it was so tall).
It was a nice bike and I have fond memories of it, but it was a little more buzzy than I wanted at speed (and it really liked to just sit at 70-90 mph).
Nice solid bike though.
