I’m with you on the R90S, although I’d lean to the R75 as that was my ride for a long time, all the way back to the point where I was in an actual “Airheads” club in the mid-90s. I still love my RT, and I logged a helluva lot more miles on the R1100 than I did on the /6…if I’d been ~1 foot shorter, I’d probably have glommed on to the Ducati, because those bikes are the embodiment of lust and power.
Bonus points for riding a beemer happen with every third person who asks about the bike: “Well, I didn’t know BMW made motorcycles!”
