Sport tourer: Nothing that I can speak from experience on....but the Yamaha FJR1300 has been getting good reviews. Or, just to be different, a MotoGuzzi Norge would be unique. If the lines of the F6B weren't so attractive, I'd have given the Norge a shot despite the limited dealer network.
Sport bike: Again, I've not put my butt onto the latest offerings from Japan...and am too old to be on a Ninja/Hayabusa thing anyway. (Though I think the Hayabusa's are gorgeous.) I've found handling heaven in the MG V11 Lemans, it too makes me grin just looking at it in the shop. Shaft driven, easy to work on, and eye candy to boot! Slightly aggressive seating. Low mileage examples come up with surprising frequency.
