How many have read this excellent tome by former racer Keith Code? What did you get out of it? I've been on sportbikes about 6 years now and I'd say about 90% of it I had figured out on my own or learned from other riders.
There are a few points however that I am trying to incorporate into my riding style. I think the books are helpful but there is still no replacement for miles in the bank.
One thing I did notice, a lot of the info is track oriented, some of it transfers to the street and back roads rider and some might get you into trouble.
He talks a lot about survival reactions that will get you into trouble and how to defeat them, like target fixation, that's good stuff. His discussion of choosing reference points works on a track but won't help much on a fast, flowing road you've never been down before. Different skill set involved there and you must hold back more in reserve.
