Know the curve !
Most of us who ride enjoy a good roll through a set of twisties. The most imoportant thing to do is to not try to be aggressive through a curve that you dont know. If you have never been through a curve, observe the speed limit postings the first time you go through them. There are many dynamics that go into approaching and navigating a curve. The camber or degree across the road has a huge impact on how much you can lean and where it will direct you as you navigate through. Leaning into a curve and catching your running boards will send a thrill through you the first time it happens and will cause you to correct your line through the curve. This can send you into the other lane or into the shoulder if you are going too fast.
The best advise i can give you is learn the roads you ride repeatedly and enjoy/ play on the curves you know, and respect the ones you have never ridden through by slowing down.
