Small sport bike (tuck) motorcycle with rider has a Cd of around .50-.60 and CdA 3.0 - 3.5 ft^2. Changing something like the mirrors and adding a boat tail trunk on the passenger seat is easily doable. Every little thing helps. Modding to a full stream liner is way beyond my plans for this brand new bike. See one of the few published articles I have been able to find on a motorcycle wind tunnel comparison.
