This is a broader claim than the one I made.
> A high side happens when the rear tire breaks traction at lean, and is no longer able to hold the arc it’s trying to turn on. [...] Then catches traction, and that z axis rotation and gyroscopic forces becomes a violent flick to stand the bike up straight.
How much lean? And how much traction loss / for how long? What if there's just enough to where a high side doesn't occur and the bike/rider don't fly off? Will the bike instantly right itself with no overshoot, without any sort of steering column oscillation? If there is an oscillatory response, what do you call it? What do you call it as you gradually reduce the lean angle to 0?
At near 0 lean angle, is this oscillatory response meaningfully different from the oscillation of a speed wobble?
