BSA 1956 500 c.c. O.H.V. model B33
A powerful single-cylinder model which has for so many years and on so many occasions proved the truth of the saying - "You can leave it to your B.S.A." The high power-weight ratio of the B33 with its 500 0.H.V. engine gives this machine an exhilarating performance.
