countersteering help
If one were to project imaginary lines (for each tire) from above the rider to indicate the orientation of the tires relative to the arc of the turn, the rear tire would be at a tangent to the arc, so on it's own, it would exit the arc. The front tire would be facing left, albeit slightly, and following the arc.
If I understand you correctly, in your scenario, the front tire's line would be facing even more away from the arc than the rear tire. I promise you, if you are in a left turn and leaning left, and then pressure the left bar, you will have a very bad day
Counter steer to initiate, then steer. Simple.
This guy -

has literally written the book(s) on this, and many related topics. My statements are based on his teachings and do not originate from me. That said, as they say, he has forgotten more about motorcycle safety and riding than I will ever know.
i disagree as well. harris neill, a motor instructor out of colorado, says it best:
You can figure out how countersteering works by thinking about this. Imagine the motor standing still and perfectly balanced, so it is upright. If you then pushed forward on the left handlebar, the motor would topple over on it left side. Of course if you pushed on the right, it would fall to the right. This is because of the “trail” of the front end. The contact point of the tire is behind the point where an imaginary line, through the steering head and front axle, intersects the ground. (The distance from that imaginary point to the contact point is the trail by the way). You can more clearly visualize the physics involved if you sit on your motor and have someone stand, facing you, with the front wheel of your motor held firmly between their legs. Note the alignment of the steering head (a straight line). Push away from you on the left bar, and watch how the steering head moves to the left. Push away on the right bar, and note the opposite effect.
The goal you want to achieve on a curve is to set up properly so that you make one positive push at the beginning of the curve, hold it through the curve, and make one positive push at the end to straighten up.

Counter steering happens at around 12mph-20mph and higher. It happens naturally, if it didn't, you wouldn't be able to negotiate a corner at any speed greater than about 12mph. Knowing how to use it effectively is important during emergency situations as you can very quickly swerve clear of obstacles. It's important in non-emergency situations as well, but happens more intuitively.
Push left, go left...push right, go right. Knowing how much pressure and throttle to apply comes with practice.
As for the technical reason as to how it works, the gyroscopic effect of the wheels (all the rotational mass) makes the bike want to continue upright and in a straight line and is the reason that force is required to steer the bike. When you push the handlebar, it moves the center of mass out from under the bike and causes the bike to lean in that direction. When the bike is leaned over, front end trail causes the front tire to turn into the curve which causes the bike to corner. When the corner is complete, use counter steering in the opposite direction to put the bike back upright.
So when you're coming up on a left hand sweeper. Slow to your entry speed prior to entering the corner. Upon entering the corner, push left on the handlebar to initiate the turn and begin to accelerate steadily (this sets your suspension). Accelerate smoothly through the corner. Upon exiting the corner, push right on the handlebar to stand the bike back upright and continue along your way.
Tail wagging does not require counter steer...it's called steering into the skid as you're doing nothing more than maintaining direction. There is no brain trick involved; centrifugal force has nothing to do with it as it is just the effects of inertia in connection with a rotational force so effectively it's just the feeling you get when you're in a corner. Moving the center of mass out from underneath the bike is what causes the lean, not centrifugal force.
Body (weight) steering can also be used, but is slower and, as the vehicle weight goes up, considerably less effective. Don't even bother with it unless you're on a Huffy.
Do yourself a favor...pick up Proficient Motorcycling or similar type of book or a DVD like Ride like a Pro, and read / watch it. Also, don't overthink it...the fact that you've been able to corner before shows that you're doing it...just start paying attention to it.
"If I understand you correctly, in your scenario, the front tire's line would be facing even more away from the arc than the rear tire. I promise you, if you are in a left turn and leaning left, and then pressure the left bar, you will have a very bad day"
If you are not countersteering through the entire turn, you may not have a bad day, but you WILL get to see how well your bike handles off road.
Countersteering isn't an option. It's the *only* way you negotiate turns and curves at speeds over about 5 mph. There are no other options. You can't ride and not do it. If you attempt to turn your front tire in the direction you want to go, you will cause it to go in the opposite direction (at the very least), or if you try turning it far enough, you'll wreck.
Just ride and don't think about it so much in regard to turns and curves. As a method to quickly change direction to avoid an obstacle or crash, go to an empty parking lot and practice, practice, practice.
FTR you can negotiate curves without countersteering by leaning, but it's not nearly as predictable or efficient. I do it when I'm riding with no hands on downhill runs (seriously)

Been riding 45 years and log 5 digits every riding season. I'll put my experience and skills toe to toe with yours any day.
And it hasn't escaped my attention that most of you have a lot higher post count than I do. Who is the internet king and who actually rides?
I'll wager Challenger has it right - you pretty much know it all. No one's going to tell you anything.
I have brought this up to young riders that I work with and they give me that stare like WTF? are you talking about. I always get a laugh out of it.
