OK, it is modified quite a bit from the stock Busa shape, but my original point was that the stock Busa shape is as aero as you can get in a production high performance motorcycle - even though it's not particularly aero.

Streamlining, for economy or top speed, is meaningful in this discussion IMO.

Even though it required massive HP to go 311 MPH, aerodynamics and drag reduction are still major factors - just like they are when striving for maximum economy.

The 311 MPH Busa's overall shape and aero improvements could still be beneficial to someone with a 250cc engine striving for 100 (200?) MPG, so it's worth discussing.
