Also think about how you are hanging onto the bike while leaned over. If you are able to wiggle your fingers on the controls mid corner, then you are not using the bars to hang on. If you are unable to do that, perhaps think about how you are connected to the bike. Outside knee against tank, inside heel against heel guard, and ball of inside foot on the peg. The more stable your body is, the easier it is to maintain a soft touch on the controls and steer the bike; not fight it in the corners.
