RE: [ST] for Matt - cornering traction



DD, you never cease to amaze me.  Maybe I WOULD ride in a plane you were
piloting.........

As for the rest of the tech discussion, bravo.  Maybe after I read them
a few times I'll even understand.

 >>> the reason the lighter bikes "carry more cornering speed than a
liter class bike" is the weight.  There is less weight being pulled out
(the centrifugal force) and thus less force acting on the tire at the
same speed as a heavier mass/bike.  Thus, a higher speed can be held to
bring the tire up to its traction threshold <<<

    Actually, footprint pressures (the weight of the vehicle divided by
the footprint areas in terms of lbs. per sq. in.) are what govern max
traction in corners,... all other factors being equal.  The difference
in footprint area of the lighter bikes is usually a lesser percentage
than the difference in weight.  Race cars can always out-corner bikes
because their footprint pressures are so much less, due not so much to
the extra two tires as to the fact that the whole width of each tire is
in contact with the pavement, instead of just the edge.
