Triumph Pre-Unit Twins
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.
