The cross wind does not turn the bike, what happens is that the bike starts to roll in the direction of the wind [force] what happens at the same is the "counter steering" of the front wheel which causes the bike to roll in the opposite direction, resulting in the bike leaning into the wind as it goes down the road. The bike is comfortable. I have only had one incident that caused some anxiety, but the fact that it resulted in no great change in trajectory gave me confidence that only a hurricane would be strong enough to cause a dangerous change in trajectory. The bike almost corrects itself, I suspect that most problems that new riders have is panic as the bike rolls.

Has anyone figured out what forces cause some motorcycles to lean into a side wind and some streamliners to get blown over? My CBR250R leans into the wind very well when ridden in a tuck. I had thought that it might be because of the cg on the roll axis being above the center of pressure when view from the side. But the "Gray" is said to behave the same way even though it has crazy amounts of side surface area, way up high.
