All the above about counterweighting, slipping the clutch, and dragging the rear brake are great suggestions.
When you're choosing where to look, for faster speed turns, I look where I want to be. That means I had to train myself not to look at the obstacles, but look just left or just right of the obstacle. For example, in the middle of a curve I see a pothole. If I focus on the pothole, I'm going to hit the pothole. If I focus to the left or right of the pothole, the bike will go to the left or right of the pothole and I will miss it.
For SLOW speed turns, you need to look PAST where you want to be. Essentially, if I'm making a right hand u-turn, I crank my head over and try to look BEHIND me while I'm turning. All the way through the turn. So at the end of the turn, I'm not looking straight, but still a little to the right of the line I want. And I keep that head angle. Cause naturally I want to look behind me and as I turn I want to see the line or curb and want to see how close I am to it. But you'll learn that if you keep your head cranked all the way, you WILL miss that curb by a good foot. Trust in the bike to have a good turn radius. Cause this bike is pretty damned nimble.
