I know it's subjective, but are these generally regarded as "any good"? Ever since seeing an R90/S parked down my road when I was a kid, I have had a fondness for the marque and the sound of those engines. But, frankly, BMW bikes in general have never really "stirred the soul" and I have never tried one. However, I can see that something like the 1100RT is (on paper at least) a really good touring bike - perhaps as a stablemate for the Sprint.
