I was thinking of a control surface, like active suspension, only it is a flap that counteracts crosswinds (like a rudder or something), or something much more complicated integrated into the aerodynamics?
so you are cruising at 60mph, 30mph sidewind hits from the right and the control surface reacts by moving its trailing edge left. not sure about trying to lever the bike level from the tail end though, it might try to swap ends if there isn't some downforce added along with the counteracting force, or if there isn't another control surface at the front, don't really know, but the idea is to add some active "flying" ability to the bike so it can react appropriately.
Assuming of course that crosswind is enough of a concern to merit such measures (not trying to be a solution looking for a problem here). I've never been in an enclosed two wheeler.
