This book is a great collection of stories and reviews of the GPz900R from various magazines over the years since 1984. A valuable resource, it shows just what mag writers/reviwers of the time thought of the bike, and has useful heads-up info on long term issues that can be addressed before they happen (such as the cooling issues with this particular bike). With this book, one can piece together a useful picture of the historical importance of the bike, and help guide the vintage re-builder. Bravo to the compilers of wisdom, I wish I had this for my other bike, a 1981 Yamaha XV920R.
