Not to be overly critical, just adding advice and some knowledge (?).

In those 2 pics posted by JWR, the body position is wrong. If you look at the pics, the rider's weight is pushing the bike down, into a higher lean angle than is necessary, as he is trying to maintain a more upright body position.
The correct approach would be for the rider's body on the bike to be more over to the inside of the turn, maybe sliding a butt check over, shoulder towards the inside handlebar, leaning over more, putting more of his weight to the inside of the turn, keeping the bike in a more upright position which means better traction on the road.The body should be leaning, head upright, causing the bike to lean less = better traction, higher speed through the turn. Check out some pics of riders racing - no need for knee down, just body weight to the inside, don't try to or fight to stay upright, that is wrong. And look where you want to go, not down on the road. Look down = go down.
