Simple physics, it's called centrifugal force. The engine flywheel is spinning. The faster it spins, the harder it is to change the angle. Do you remember in elementary school science class they had a spinning bike wheel that allowed you to hold on to the axle with both hands while it was spinning? The faster it spins the harder it is to alter the angle.
Same thing with an engine flywheel, and also the reason that the advice in every single motorcycle training course is to keep the revs up during slow speed maneuvers.

Anyhow, try reving your engine up and see if it actually stops your bike from falling over. I'm confident you're going to be disappointed.
Keeping the revs up in the slow speed courses is to keep your engine from stalling while you slip the clutch. You just need it up a bit, not wound up. I've done the courses with riders who idle their way through most successfully. If you listen to the engines of the cops doing it, you'll notice they're barely off idle throughout the entire length. Same too the BMW advanced Adventure classes, which are even more demanding of slow speed drills, it's done at near idle.

That's called gyroscopic precession. Centrifugal force is misunderstood centripetal acceleration.

But I agree, thread is off the rails 😃
