Fom is start late in 1937, the Speed Twin set the pattern for the British industry in the postwar years. Its ten year start was always an advantage, and from the basic tourer came both smaller and larger versions, plus more sporting variants. Later, they turned to unit construction, and this title directs its attention to the base, the tourers from which the rest came, the machines bought and used by so many.
