One of the newest and enjoyable reference books in my motorcycle library is "The Complete Encyclopedia of Classic Motorcycles". Besides including the obvious manufacturers like Triumph, BMW or Indian it was nice to read some non-mainstream history about Pope, Ace, Merkel, Morini and Curtis. It's also very handy to sort out all those predecessor and merger timelines that seem to dribble out of my memory over time (like Aermacchi, Harley, AMF, Cagiva, MV). Noticeably absent was my beloved Derbi but I understand the need for brevity in a book of this type. It is because of this I may take issue with the word "Complete" in the title. It is a good resource read. Any two wheeled nut should love it.
