I have been studying video and am trying to understand the physical dynamics of these two crashes. How they happen, how to avoid them and can you save yourself once one begins?
It seems in studying the low side crash either the rider leans so far as to move the tread from beneath the bike or one or both tires loose traction ( for whatever reason) at lean and the motorcycle simply “slides away”. Simple to see and understand. Do I have it right?
The High side is more complicated. Slowing down the videos it appears that the rear tire looses traction and regains it milliseconds later enough to pitch the rider forward. Correct? Why does this occur? I saw the 4/7 post of Kbacon but there wasn't a detailed discussion.
I have analyzed videos of professional riders and they seem to put the cycle in the same slide into and around corners without upsetting the machine. The front and rear tires are out of alignment the same as the guy who’s getting ready to crash yet the pros gracefully slide around the bend and exit under power. Are they keeping the rear spinning faster than the front until the bike straightens?
Repeating my above question can you save yourself once the rear tires steps out? In a video my daughter took this July 3rd at VIR South a rider coming out of turn 6 did something to get out of alignment, the bike does a big wiggle but straightens and continues.

My curiosity is more than an idle one. No rider wants to experience these events. To avoid them I need to understand them and if one happens it would be great know how to remain vertical.
