1933:


This is the year the BSA advertising people went over the top (and never recovered?), because they invented a quite absurd conversation between two chaps talking about the new BSA models. Again 12 models on offer with 4 sidecar models. From this year on all BSA motorcycles are equipped with electric lighting.
