The author continues to build upon the skills outlined and described in the first Proficient Motorcycling book.
Though this book is not organized the same.
The first book was a nice balance of "MSF" type theory, real life riding experience, drawings, pictures, and diagrams.
This book is more of a story telling best practice manual. The author tells a story of an event either he experienced or a friend experienced and then breaks down what was done and could have been improved on. Chapters range from Long Distance Riding Tactics, Mental Prepardness, and Route Selection, to Bike Maintenance scenerios, Curve Scenarios, and International Road Rules.
There is some overlap between books, as some theory needs to be explained again to be able to correllate the story to the instructions.
If your a beginner biker then you will appreciate reading this book after the first proficient book, just for the real life experiences you might expect to encounter.
If your a seasoned rider then some of the stories will seem familiar, and you may find yourself re-evaluating what happened during your ride.
I recommend reading the first book, Proficient Motorcycling Ultimate Guide, then getting some of your own experience under your belt before diving into this book. You will find the stories easier to visualize in your mind and much more memorable.
