I was a bit shocked when I read this book and saw the scope of its contents. Even more shocking, it was written in a way that I could comprehend. I've spent tweny-plus years trying to figure out motorcycle suspensions, and now, thanks to this book, I finally get it. But perhaps most shocking of all was the negative review below, which was more of a personal attack on co-author Lee Parks than it was a useful review. I've met Mr. Parks--I took his Total Control riding course and found it extremely useful. Granted, Mr. Parks may not be the easiest person to like and he can come off as slightly abrasive at times, but he clearly knows his business, and he's a top-notch writer, which shows in every page of this book.
