When cornering I try to do this:
Lean the bike into the corner
but DO NOT lean your body into the corner, keep it VERTICAL
Keep your body straight up.
What helps in achieving it:
PUT MOST WEIGHT on the OUTSIDE pedal and keep that OUTSIDE heal DOWN (lowered outside heal lowers your center of gravity and applies max pressure on the outer knobs of the tires)
Put OUTSIDE knee against the frame if needed
Keep OUTSIDE ELBOW HIGH (VERY IMPORTANT it helps keeping your body vertical, it is a good thing to use as a conscious mental check
LOOK to the corner exit point
USE Dynamic pedal idea
