Ducati's classic 750, 860 900 and Mille bevel-drive twins from 1971-1986 are now amongst the most collectable bikes in the world. Although built in relatively small numbers, there are many individual model differences that can make their authentic restoration difficult. This book serves as a definitive guide to authenticity and gives hands-on restoration tips and guidance. This range of motorcycles lasted 15 years and now a restored bike with original parts will be worth about double the value of one with the wrong parts/detailing. There have been so many little variations over the years that most people have no idea what is correct for a particular model. A would-be buyer's first question is always "how authentic is the bike?", not if it is beautifully restored or not. So this book is a comprehensive guide to authenticity. The content includes colour codes, stripe widths, decal placement, etc. The practical chapters are by necessity broad. For instance, there were five fork types, more than five shock absorber types (many not rebuildable), more than five brake types and ten different frame types.These practical chapters cover little tricks in assembly and offer general advice rather than a detailed workshop manual-type description.
