You lost my acceptance right off the bat. Maybe you mis spoke. I have observed that the wind FROM the left causes the top of the bike to roll TO the left. The top of the bike rolls into the wind. Or more apparently, due to the distribution of mass on the roll axis and the distribution of side area presented to the side wind which is much greater below the roll axis than above when the rider is in a tuck, and the fact that the new counter steering angle generated by the trail, is with the wind, the bottom of the bike rolls out from under the rider WITH the direction of the wind. This is in the roll axis. There has been no yaw in the picture yet. And there will be almost no yaw in the discussion until you put a big tail on the motorcycle. And maybe even still not with the tail unless you are forcing the rear wheel to slip sideways. But that is a whole different discussion.
