Query: Very informative for an experienced rider without formal training.

If you can't learn anything from this book then you are a very informed motorcyclist. I really had very little interest in about half of the book and the subjects covered. But the other half contained either things I didn't know or things I need to remind myself of on a regular basis. This is a book I'll keep and reread the highlighted parts once a year.
