BSA Unit Singles: The Complete Story including the Triumph Derivatives

The BSA range of unit construction singles was in production for fifteen years, and spanned the time of BSA's greatest success, to the eventual failure of the company. In that time, the range provided BSA with their basic 'bread and butter' machines, gave thousands of learners an introduction to motorcycling, provided BSA with many national and world championship wins in the off road arena, mobilized the British Army and gave trail riders the world over the means to further their hobby. This illustrated history of the BSA unit singles runs from the 250cc ohv single cylinder C15 Star of 1958 to the B50 of 1971 and includes all the Triumph-badge derivatives. Matthew Vale provides not only the history but much practical advice relating to the purchase, restoration and maintenance of these machines.
