Today I high-sided my bicycle.  Why am I cross-
posting this to net.cycle?  Well, I'm wondering what
physics are involved in high-siding.

It all started yesterday... I was tired of riding my
Specialized Touring II tires, so I put a Turbo/R on
the front and a regular Turbo on the rear (these are racing
tires -- the Turbo/R is a slick).  Both are reasonably scuffed
up -- 200 miles on the Turbo/R and 1000 miles on the Turbo.

Today I tried to make a tight, fast left turn on wet pavement and felt
my front wheel slide out.  I expected to soon be sliding
on the pavement on my left side.  Instead I found myself
rolling over on my back on the muddy grass off
the road, with my bicycle on top
of me.  I wasn't hurt -- I just got up and rode away.

I've dumped my bicycle dozens of times (and my motorcycle 3 times).
I've always fallen on the inside.  What makes a bike fall on
the high side?  When a motorcycle high sides, does it end up
on top of the rider, or is that just peculiar to bicycles, which
are a fraction of the rider's weight?
