so heres how it works...
improper foot and rider position before corner entry and prior to prepping.
proper rider and foot position prior to corner prep. (notice the feet moved back to the toes, and your ass slides to mid seat. this straitens the back and shoulders.
now to prep for your corner entry. this is where the toe meets the peg nipple and the heel rotates up onto the heel guard. this in turn allows your knee to rotate out correctly with no effort or strain.
then slide your entire body to the side of the bike (in this case, to the right) so your asscrack meets the edge of the seat and your chest is inline with the mirror.
impropper position aka being crossed up
from there you will then lean your body forward and bend your inside elbow and straiten your outside arm.
the outside arm and leg should look like this. the elbow straitened but not locked, your knee griping the tank and foot slightly forward on the peg.
then relax your body and lean the bike into the turn while looking over your elbow and remaining tucked to the inside of the bike.
at this point alot of riders and some new racers are sketchy about hanging off the throttle side because there right hand and arm are unpredictable with maintaining body posture and control. the usuall mistake is this when the body is positioned but the hands are not. notice the bent wrist. causes strain and hard throttle control.
the best hand position is this... it maintains control and is totally strain free. quite comfy too.
