It really disturbs me that even the Wikipedia article on countersteering completely ignores the gyroscopic effect, and the article at the beginning of this post does as well, and thus comes up with a completely nonsensical explanation for why motorcycles stay upright on the road.
Countersteering is most easily explained by the gyroscope phenomenon known as "precession". While the change in the contact patch explains why the bike turns, and partly explains why the bike will lean into the turn, the actual reason that countersteering turns are so effortless, and why countersteering works only at higher speeds, is because the wheels act as gyroscopes stabilizing the bike. You can try this yourself at home with a bicycle wheel to see exactly what happens when you countersteer: Hold the axle of the wheel in both hands. Have a friend spin the wheel so it is turning fairly quickly. Then, simply "push" with one hand and watch the wheel roll over into a smooth turn (and lean) in the opposite direction. The steering geometry helps the bike recover after the turn. Additionally, this also explains why accelerating out of a turn helps bring the bike back up, as the added energy allows the bike to overcome the gyroscopic effect of the front wheel.

Thanks for such an amazing video which made the concept of counter-steering clear.. Its really very easy, You just need to watch your back and sides before doing it in a City ! ..As the guy in the video said, we've done this n number of times in our day to day riding ! .. We just didn't think about it :P .. Again, Thanks for such a nice Video ! Enjoy ! |
