1933

This is the year the BSA advertising people went over the top, because they invented a quite absurd conversation between two chaps talking about the new BSA models.
Again 13 models on offer with 4 sidecar models. The G33-12 Light was not in the main catalogue. From this year on all BSA motorcycles are equipped with electric lighting.
