Twist of the wrist is fantastic, as is the video, which can be found on YouTube. Agree with everything you said, and I'm curious: what do you ride? I've been tracking a mostly-stock R6 for the last 5 years, A the last 3 or 4. One thing I thought I'd add is that with motorcycles, the rider is a significant fraction of the total mass, so your position on the bike can greatly affect the center of gravity. You see guys leaning off the bike (towards the apex of a corner), which allows the bike to stand up taller, thus requiring less lean angle/more contact patch, which allows for higher speed and better grip at corner exit.

Oh and another surprising thing: on track I never use the rear brake when braking hard. Why? Hard braking lifts the rear wheel, and when you use the rear brake it becomes incredibly easy to lose rear traction!
