You would normally make a right turn, for instance, by simply leaning to the right. But if you need to turn on a dime, that is, really sharply, as you would if a car cut in front of you at an intersection, a quick flick of the handlebars toward the left, then a lean to the right will get you into a 90-degree turn that could save your life.

A bicyclist actually subtly turns the handlebars the opposite direction briefly to make the bike lean in the correct direction, then turns the handlebars in the direction of the turn to stabilize. It's called countersteering: http://en.wikipedia.org/wiki/Countersteering According to the Wikipedia article, bicyclists almost do this unconsciously, while motorcyclists have to do it strongly and deliberately due to their higher speeds.
