Classic Motorcycles & Triumph Pre-Unit Twins 2 Book Set

The book is the fruit of hands-on experience gained in the workshop as well as knowledge gleaned over years of consulting books, manufacturers’ manuals and specialist magazines by one of the leading technical journalists in the sector, Massimo Clarke. It is intended as an easy-to-read guide with clear, precise contents regarding the restoration of classic bikes, with attention being focused not on pre-war models but those from the 1960s and '70s, those on which we still work most frequently today.

All aspects of restoration are dealt with special reference to mechanical work on the engines and the chassis components, those which enthusiasts can do themselves in their own garages, using tools that are easy to find at reasonable costs. The book is enhanced by an in-depth examination of the reassembly of the crankcase and two chapters dedicated to the final drive and the spark plugs. A guide of fundamental importance for those who want to “get their hands dirty” around their classic bikes. Triumph's pre-unit twin-cyclinder motorcycles were produced from 1938 to 1962, with engine sizes of 350cc, 500cc and 650cc.  Ridden both on the road and in competition , the bikes formed the basis for Triumph's success through the 1940s to the 1960s.  With iconic names such as Speed Twin, Tiger 100, Trophy and Bonneville, the pre-unit Triumphs came as sports bikes and tourers.  With their superb styling and reliable engines, there were a favourite both at home and abroad. Triumph Pre-Unit Twins looks at the history and development of these bikes, and describes the various models that make up the range. It gives a detailed technical analysis of each model.  Interviews with past and present owners give riding impressions of the bikes both today and back in the 1960s.
