BMW R nineT
I don't own one of these, but was able to ride one at a Max BMW (South Windsor, CT) Demo Day. With an 1170 cc boxer engine rated at 110 horsepower and 86 ft-lb of torque, this bike gets up and goes. Lots of fun to ride in nice weather.
That said, it is very different from the RT touring bikes - no fairing, very basic instrumentation and no provision for bags.
