This book was written with parents in mind. My goal was to help them deal with the routine of caring for dirt bikes and to encourage interaction between parents and kids. The "maintenance monster" is the toughest part of the sport and it's the biggest source of emotional stress between kids and parents.
The information covered in this book ranges from basic to intense. Each chapter starts out with basic things that anyone can do and wraps up with tips geared for professional race mechanics and tuners.
If you're new to the sport and haven't purchased a bike yet, the first few chapters will help you figure out what is the best bike for your riding needs and how to evaluate used bikes, purchase a new one, and perform the basic maintenance necessary to keep it running.
The middle chapters of this book will introduce you to the major maintenance issues that need to be addressed in one- and two-year cycles unless you are racing, then it becomes a weekly routine.
Finally the last group of chapters deals with specific models, which parts are likely to break and why, and how to correct these flaws with the best aftermarket accessories or original parts.
