The first ride I ever did on a "big" bike was on the back of an R90. Ever since that day, I wanted a boxer BMW. It was like a spaceship compared to my two-stroke KE125.
Bought a black '02 R1150R and liked it a lot. Very versatile and comfortable bike, and I do miss that boxer motor now that it is gone. I suspect I'll have another. I love the old airheads.
Those servo brakes were great in terms of operation, but man, what a pain in the !@# to work on. The $2k replacement cost for the pump scared me, along with lack of nearby dealer support (both of our Kawi dealers are gone now, too). I saw a deal on an FJR and didn't hesitate. FJR felt like a bit of a step backwards in handling and braking (and weight), but a huge step up in power and wind protection. Harder to work on but needs less frequent work.
