Overview[edit]

BSA B "Round tank"





BSA was justly proud and underlined their pride with a bold fuel tank finish. In keeping with period trends the tank served both fuel and oil needs, but its cylindrical shape bucked then current trends, looking as though it ought to grace a lawnmower.

Instead of hiding it, BSA painted the tank bright green and emblazoned it with panels, lines and logos.  And it is the tank which gave Model B its hindsight name. As many British moped and two-stroke riders from the 1950s and 1960s know, riding a small low-powered machine makes you the lowest of the low in the eyes of some.  No different in the 1920s and along with the sarcastic comments Model B riders copped for a few including famously mower tank, marrow tank, cucumber tank and round tank.  Round tank stuck, BSA successfully banked this inverse praise and Round Tank owners are justly proud today.
