BTW, here is a tid-bit of info I found on the web about rider leaning/ground clearance:
Why do Road Racers Stick Out Their Inside Knee?
It lets the bike lean less for a given speed. By sliding off the inside of the seat, the rider's body weight is moved towards the inside of the corner. This means the bike needs less lean for a given speed and turn radius. As ground clearance is often the limiting factor in cornering (particularly at higher speed) this allows the rider to corner at higher speeds.
Here's some nerd info that describes turning geometry:
T = arctan [V^2/(G*R) ]
V is your velocity, R is the radius of your turn, G is the gravitational constant. T is the "lean angle." It's the angle between (1) the horizontal, and (2) a line from the contact patch of your tires through the center of gravity of the bike-rider system.
Hanging off and sticking out your knee moves the center of gravity of the system to the inside, while leaving the bike more upright, so you don't run out of ground clearance.

I see your point devil & you're right, that would be the mathematical way of cornering as far as geometry goes. I've got old habbits, been ridin dirt bikes since I was 6 & in no way am I willing to change (that would completely fu**me up)! Throw my leg on the dirt bike & swing my knee on my dyna, been doin it for years & never had a problem cornering. Sh** dude I'm so used to it, I bet if I tried your way & hung off the side of my seat to corner I'd probably crash! Lol
