maybe you already do this, but if you don`t...
as you head into a corner push down on the pedal with your outside leg, and push down slightly with your inside hand, on the hood/bar - this will give you a far smoother line on the corners, and you`ll find that your body perfectly aligns itself into the corner.
as your confidence grows with practise you`ll soon find that you loose that wobble that comes from improper technique, your speed will increase and you`ll actually feel much safer, as your ability to `hit` the optimum center of gravity improves.
good luck!
