This edition is one of a series of books in the “Illustrated Buyer’s Guide” series (such as the BMW Buyer’s Guide described above), which use a similar format to describe and illustrate a particular marque.
They are successful because they have just enough information to delight anyone other than the true aficionado.
This book focuses primarily on the post-war evolution of Triumph motorcycles, right up to the modern Hinckley triples and fours. It seems to be a bit weak just where it shouldn’t be — in it’s coverage of the famous Bonneville. It takes a bit of study to really understand which year produced the best Bonnevilles, as the author’s description of their history gets a bit muddled. This is a very good guide and reference for either the casual or serious Triumph fan.
