You know, I was really hoping they'd counterbalance it instead. The Sportsters get their "sporting nature" at least in part from the solid mounting of the engine. Well, that, and to prevent the frame from twisting up like a pretzel.
Still, after the Twinky engine, we all expected that they would have to do *something* to the Sporty. And, really, pretty well anything is a help. I wouldn't actually mind seeing the 984cc Buell motor in a version of the Sportster, myself.
