I could have said slow ride practice seems to help at all my speeds and all my maneuvers. The bike is always changing lean angles, it's aways grabing or giving up a little traction.
Practicing correctly helps. You draw conclusions that more skilled riders disagree with and sthen stand firm that you are correct.
I'm noticing my ability to control the bike has everything to do with what I can feel. If I can't feel it I can't do it.
Bummer that you limit yourself to what you can feel. Your focus seems to misdirected.
Slow riding seems to be a useful core exercise that you never out grow. I envy the balancing abilities of the trials riders.
It can be useful at low speeds, but once above 15-20mph, the
balance skill of the rider are a miniscule part of the skill required to ride.
That is a big problem with your
practice.
Which begs the question of what particular skill deficiencies.
Judgment. Not looking far enough ahead. Relying on body position to control lean. Fear/panic.
In practice I've been exploring rear wheel traction, how to increase and decrease it and I'm impressed by how little effort it takes to unhook the rear by subtle changes in power, weight distribution, roll rate, etc.
This is a skill, but not one that is useful outside of a controlled environment (parking lot, racetrack, dirt riding area).
Driving a car is valid experience for situation awareness but it is zero preparation for the skills needed to maneuver a motorcycle anywhere near it's potential.
You couldn't be more wrong. The input to the controls may be different in a couple of areas, but everything else is the same. Look well ahead, complete your braking before turning, accelerate through the turn. Path of travel is the same, where to look when turning is the same, smooth control input is the same.
When you invoke your "dangerous" argument you step over the line. Riding a motorcycle is not a religion and you are not a priest. I could be right, I could be wrong. Understanding is crucial to proficiency on a bike. Blind following undermines that. If you want to disagree do it on the merits, not with logical fallicies, ie.
The irony of you asking someone to give up logical fallacies is sad. These fallacies are a large part of what you teach yourself and share here.
Practicing it isn't a panacea, just a very useful lesson.
Only if doing it correctly and properly interpreting the results.
