    Not often, but after a real hard night on the bourbon i have to be carefull not to force it !
    A girlfriend once asked " Why is it you seem to prefer to race, than spend time with me ?"
    The answer was simple ! "I'll prolly get bored with racing too, once i've nailed it !"

    Nah it's because you were doing over 100kph. Speed kills dont ya know. The wind knows this too so decided to punish you. Under 100, it would have left you alone.
    Watch out for tow ropes and quickly braking cars

    lol, ironically I find that the faster I go the more stable the bike....

    If ya wanna try something fun in a strong crosswind, pull a ZX12 into a wheelie on the downwind side of the median barrier and tell me what happens when the front comes up above the level of the concrete

    Entertain this. If you don't move the bars and there is no pivoting of the bike around the steering head and you lean the bike (either through CoG movement or wind) the bike will keep going in a straight line..
    How about the laws of physics?

    A body in motion will continue at a uniform rate and direction unless acted on by an external force.
    The poor boy was acted upon by the wind. This brought into effect the principles of friction and second class levers.
    The external force acted upon the whole moving mass, but was reacted to by friction between the tyres and the road. this friction therefore had a fulcrum at ground level, and the resulrant force then pivotted about this fulcrum.
    This pivotting action placed a tilting action upon the wheels, which then followed the principles of gyroscopic precession, and tried to move at an angle 90 degrees after the action, and went sideways.

    It's a complicated business this riding, just be grateful that most of the time you're ignorant of what's going on, and therefore are not distracted by complex equations of inertia, vectors, thermodynamics etc.
    In fact, the thicker you are, the easier it is to ride. Therefore, one way to replicate this is through copious use of mental relaxants such as Steinlager......

    Ride safe, get wankered

    .....aint just little bikes that get knocked about....our goldwing has about as much sail area up into the wind as a small yacht...can become a real physical thing to keep her going where you want her to go at times...mainly big canterbury nor westers are the ones....just go yehaa and work the bike....my wife had a bit of a problem with it...as soon as she learned that loosening up and pulling yer head and shoulders in was the way out of feeling like the wind was in control. she was ok....

    Sorry. A bike can be leaned and still track straight. The steering head must pivot, even only slightly, for the bike to 'turn'.
    Crosswinds tend to act more on the rider, and it is what the rider does that has a greater effect on what happens to the bike in terms of veering to the side.
    Do you realise how many holes there could be if people would just take the time to take the dirt out of them?

    You don't need to understand the laws of physics. Simple cause and effect will do. that's all most people can handle or need to understand "what" will happen. what is useful to the user, why is useful to the designer. Most of us are users (some moreso than others).

    Pivot at the steering head (regardless of whether the force was caused by wind pushing on the frame, or body twisting the handlebars) will make the bike turn.

    Disregarding the tongue in cheek post I wrote, go see your local toy shop and buy a gyroscope.
    If a rotating mass is displaced from it's normal plane of rotation, the net effect is an action at 90 degrees following the input.
    And if you lean the bike without counteracting it with weight acting the other way, then the simplest laws af gravity and levers will make you fall over.

    Please, oh God, pleeeease, take it as intended and don't try to get into a debate. I am big, and I am clever

    True, that. But a cross wind wouldn't necessarily make a bike lean. The effect is more on the rider. So what the rider does to counter the wind has more effect on what the bike/rider unit does.

    Shall we say that we are both right?

    I'm not sure what you intended anyway, as I don't know whether the OP wanted a physics explanation. Your grasp of physics is definitely superior to mine, and I cannot disagree with what you say.

    I don't think he did, but I was well into my second bottle of cheap wine when I read the OP.
    I particularly like the fact that you agree that I'm clever!

    Anyways, I shall henceforth refrain from this post, I need to control my drunken postings again......don't need tyres yet!

    The wind wasn't trying to kill you. Nature was trying to give you a blow job, but you just weren't ready.
