I found this book to be a great help with preparing to ride on the track. It goes over all of the basics (safety wire, suspension, protective equipment, etc.). Also, the author's writing style was humorous and kept me entertained.
My only complaint was the section on entering roadracing on a small budget. He talked of so many add-ons that, in my opinion, it was not low budget. He did say that you can race a stock bike, but did not discuss what you would need to do to prepare the bike for racing.
The author's level of riding also seemed pretty high before he started riding on the track. This gave him higher expectations of his abilities than I believe most people should have.
Again, I thought this book was excellent.
