I also have a new theory. I suspect that countersteering is more
pronounced the heavier the two-wheeled vehicle is. On the 1000 lb
Harley (bike and rider) the effect is very pronounced. I suspect a
smaller, lighter dirt bike would not exhibit the effect to the same
degree.

I suspect you are right. That big Harley front wheel has more of a
gyroscopic effect, which I'm guessing is instrumental to the counter-
steering phenomenon. The push left gets your left lean, but the
gyroscopic effect means the wheel will straighten so you can continue
your left turn. The same physics apply to a bicycle, but because of less
mass they are not as pronounced. At least that's the story I'm sticking
to.
