When you countersteer, it may seem as if pressure on the grip pushes the bike over without actually pivoting the front wheel. Does the front end actually pivot away from center as the bike leans over into a curve? Yes. The movement is slight, but if the front end isn’t free to pivot in the steering head, the motorcycle can’t be balanced or turned.

If you could watch a slow-motion video of a motorcycle running through a puddle of paint and then making a turn, you would see that the front tire momentarily tracks toward the outside during the initial countersteer, then eases back toward the direction of turn. In slow-speed turns, the front tire generally tracks outside the rear tire.

When the rider countersteers, the front wheel momentarily out-tracks opposite the intended direction of the turn, then returns to center as the motorcycle leans over.

If you’d like a good example of out-tracking, record some motorcycle road race footage, and play it back in slow motion. In those shots where the camera is looking back down the straight toward a corner, you can see the lean angle of the bikes head-on. If you mentally plot the path of the motorcycle’s center of mass, you’ll see that the bottom of the front tire out-tracks, even arcing over onto the rumble strips as the rider uses every last inch of pavement to get the bike leaned.
