Birmingham Small Arms (BSA) produced cycle parts of the highest calibre to British and foreign manufacturers years before they took the natural progression to producing complete motorcycles in 1906, their first offerings being single cylinder machines that were little more than motorised bicycles.

The factory quickly progressed to making proper motorcycles and by 1921 were producing their first large capacity (770cc) V-twins, going on to become the UK's best known bike manufacturer, producing machines for all tastes from mopeds and scooters to pure sports and competition machines.

The motorcycle offered here is a 1953 BSA B31 350cc machine with a sprung ‘plunger’ frame. This was one of BSA's earliest attempts to produce a rear sprung frame which offered a little more comfort to the rider and passenger, and as such sports the optional dual seat for a further attempt at some form of comfort. Coming from a private collection where it has been since 1986, the machine appears to be a complete and unrestored example that is nicely patinated.
