With the popularity and prices of vintage Triumphs at an all time high, a lot of people are looking for that perfect Triumph to bring home. Triumph Motorcycles 1956-1983: Enthusiasts Guide, starts with a short history of the most common and popular of the Triumph Twins and Triples, those built between 1956 when the first TR6 was introduced, and 1983, when Triumph Motorcycles LTD filed for bankruptcy. This new enthusiast s guide for Triumphs breaks down each model, the TR6, Bonneville, Thunderbird and Triples into smaller sub-groups. The first early TR6 models are presented together as there was very little change from year to year. The 1959 Bonneville, however, is presented alone, as that particular bike used a large number of unique parts- parts that were only used for the one introductory year. Each listing starts by describing the models in question, and then goes to great lengths to help the reader in making sure the important parts are correct for that particular year or years. Details include photos of speedometers and tachometers, which often changed year by year. Also covered are items like the exact year the battery box changed on the TR6 line, and which models, in which years, used aluminum, stainless or painted fenders.
