For those who don't know who Keith Code is, you should know that he knows alot. He is the head man at California Superbike School and does he know a lot of important information. I have been reading one of his books, Twist of the wrist II". It is a fantastic book and can definitely help improve your riding skills. I am only thru part of it and I have already learned so much and my riding has already shown improvement. If I can ever afford it, I will attend his school. Anyways, it is great information on anyone who rides aggressively or even helpful info for those who don't. I just wish that I would've had this book years ago.
