It was pampers time I can tell you. > Oh for a heavier bike.....There is a skill to riding in heavy gusts without being diverted too much from course. I've got rather good at it, and one important factor is hloding the bars lightly, and beiong careful not to allow _you_ being hit by the wind to get translated into a tug on the bars. It helps a lot to have narrow low bars, in which the line between your hands passes through the the steering axis, which reduces your wind profile, your leverage, and permits you to hold yourself against gusts with a double-handed grip without imparting a steering moment. I suspect this is far more important than the weight of the bike, since my very light Ducati 450 single (lighter than most 250s), with clip-ons, was very stable in heavy gusts. I suspect the line-up of hands and steering axis to be the most important factor.
Once you have mastered not applying inadvertent steering (much easier with the hand-axis line-up), you then concentrate of applying rapid countersteer to offset each gust. To begin with you do this in response to the bike leaning over. As you get better you learn to do it in response to the wind hitting you, before the bike has moved too much.
You know you're getting the hang of it when the bike flips seriously from side to side in response to the gusts, but doesn't actually change its line a lot.
