BSA announced their post war range, consisting of four models, in August 1945, headed by the sporting B31. The new model was derived utilized the M series crankcases endowing it with a "bombproof" bottom end fitted with an over head valve top end. Early models relied on telescopic forks and saddle springs to provide rider comfort and it was not until 1949 when the machine offered was built that the option of a plunger sprung frame became available.
