Counter-steering, leaning, and using massive throttle to steer the motorcycle from the rear is currently the quickest combined technique to change direction of a motorcycle. Of course on the street most people will not do the third part, so Counter-steering and leaning together will always change the direction of the bike faster than Counter-steering by itself (on the street). On the track, the best racers use all three combined. It doesn’t matter if you’re riding a Harley or a cutting edge Sportsbike, I strongly recommend practicing both together.
