As someone learning the balance point on my sumo, what's the physics behind that?

Physics behind a tank slapper, or the balance point?

Google tank slapper. It's simply an oscillation of the bars caused by irregular pavement/rider input on the bars/magic.

One thing I learned at the california superbike school, if you get into a tank slapper, LET GO, just let go of the bars, hug the tank, the bike will right itself....physics, it's cool.

Don't believe me? Watch race videos of tank slapper crashes, in most of them as soon as the rider gets bucked off the bike the bike immediately corrects to a straight line and rides off into the distance riderless.

Good question, it's very simple. If you watch the technique in the video, you will see that once on balance point, he cranks the bars over to the left and holds it there. This motion actually 'locks' the wheelie in to place and allows him to hold it on the rear wheel. This is what all seasoned wheelie'ers do... the only slight side-effect is you will always end up in a tank slapper when you set it back down.
