without full front and rear fairings to encapsulate the driver, motorcycle aero sucks.
Note, all the smoothness is for naught.
I tend to prefer naked bikes just to keep it simple, or vetter style full enclosure/recumbant. Something that looks streamlined sitting still, but isn't when you add a rider is not well thought out aerodynamically.
(and yes, I recognize the previous post as a prelude to spam)
