Review:

This is a reprint and updating of his Speed Twin book, but this time it carries on by describing the factory's response from it's American customers for more power by increasing the 5T engine's capacity to 650ce and thereby creating the 6T Thunderbird. Harry then gives a year-by-year breakdown of the 6T model's details, some of which were previously unobtainable, up until it bows out in favour of the TR6 Trophy in 1966. Photographs there are, in plenty of both models, and as the book is a large, glossy-paged hardcover this time the photos are of better quality, some being also in colour. That famous photo of the Met Police on their Speed Twins passing the rostrum on which the Royal Family are sat during the 1946 Victory Parade is in colour, the first time I have seen it as such, though it does have the look of being hand tinted. All this is interspersed with anecdotes of speed and reliability tests carried out by the factory, along with competition successes, and there are reprints of road tests and pages from various brochures, not to mention details of carburettor spec's for both models, a page of gear ratios from 1938 to 1966, lists of show models, colour charts and so on. The book is a worthy addition to the TOMCC Member's personal library, making a good read for its historical value even if you don't own either of the two models. --Nacelle magazine, January 2005

Jeff Clew used to commission motorcycle books for a living, and he's written more than his fair share of the things, too. So when he recommends this new Triumph bible, you can take him at his word ... The mass of information contained within the 144 pages of this book is well laid out and easy to follow, with many good quality instructions and some nostalgic full-colour copies of Triumph catalogues. Also included is a brief history of Edward Turner's revolutionary Speed Twin, and an account of the launch of the Thunderbird in September 1949. I had the privilege of commissioning Harry's earlier work on the Speed Twin, published some 15 years ago, and I can confirm that this greatly enlarged edition is much more than an update. Not only is it now in larger format but also better presented on good quality paper, with the added benefit of the inclusion of similar detail on the Thunderbird model, and a bonus from the addition of colour. To anyone owning either of these models, I see it as an essential purchase, especially when no effort is spared while rebuilding either model as closely as possible to its original specification. Owners will also find it an invaluable source of reference over the years, to be consulted again and again. --Jeff Clew from Real Classic, November 2004

About the Author:

After National Service in the Royal Air Force Harry Woolridge applied for a job in the Service Department at the Triumph Engineering Company, and was lucky enough to be selected. Thus began a working relationship with Triumph and its motorcycles that would last thirty years: an experience Harry says he would not have missed at any price. After a few years in the Service Department, Harry joined the team in the Experimental until he was promoted to the position of Assistant Quality Control Manager. Later, in a reshuffle of titles, he became Inspection Foreman for Motorcycle Assembly and Production Development. With the formation of the Meriden Co-operative, Harry served as Warranty/Service Manager until the factory closed in 1983.
