Isn't this essentially the same reason it's harder (takes more force)
to turn a corner when you're going fast (greater linear momentum)?
In this case it's angular momentum (sorry Sam). Tipping changes the
angular momentum of the wheel and so requires more torque when the
wheel is turning fast.

Indeed the angular momentum becomes WAY more important on a motorbike with greater speed and moment of inertia.

When riding a straight path at speed - making a quick turn to the LEFT requires the rider to PUSH FORWARD on the LEFT handlebar. This is hard to explain without resorting to Sam's nasty Angular Momentum.

(The steering effect of the the tires profile can be well illustrated with two foam cups taped together rim to rim. The double cone steers as it is tipped. none angular mom. effect)
