Dude.
Consider writing in actual, you know, like, sentences. With, like, punctuation and stuff. Try it. We're beggin' ya.
To the OP: Leaning your body is not what makes the bike turn. Countersteering is.
You feel like you're going to fall probably because you're not on the throttle through the turn. Remember in MSF how they told you to accelerate through the turn?
Rule 1: Once the throttle is cracked open, it is rolled on smoothly and continuously through the turn.
That does NOT mean you're going from full throttle to wide open. It means that you do not cut the throttle. On a supersport it means just gentle, SLIGHT pressure to keep the bike accelerating JUST A BIT. As in if you whack the throttle open you're going to wind up in the trees. Get it?
How to corner: Note that "lean your body" is not part of this:
Get your speed down before you tip in. Look where you want to go.
LOOK WHERE YOU WANT TO GO.
Did I mention that you should look where you want to go? You go where you look. Look down, go down. Look at the spot on the pavement where you want the bike to wind up, and you'll go there. Really, no kidding.
Countersteer to tip the bike in.
Crack the throttle open and roll it on through the turn.
Really, that's it.
Don't focus so much on leaning. Focus on cornering. That's not the same thing.
Lean is a byproduct of cornering, not the goal. The goal is to make it through the corner. The lean will happen by itself.
Ask yourself what your actual objective is. Is it to look cool, cranked way over with a knee dragging? Or is it to improve your riding and be smooth and quick?
If the former: What are you, stupid? Is this a fashion show or something? And why the hell would you want to do something like that on the street? Take it to the track.
If the latter: Good man! That's the right attitude. Now… why do you care about leaning? Shouldn't you care about cornering?
