A Thunderbolt from the USA
WORDS AND PHOTOS BY PHIL MATHER
Imagine, for a moment, that it’s 1962 and you’re in the market for a brand new motorbike. BSA has recently launched its all-new, unit-construction twin-cylinder range and so you’re off to the Motorcycle Show at Earls Court, London, filled with anticipation.
In marked contrast to the old bits and pieces design of the earlier A-series twins, BSA has now produced a ground breaking ‘power egg’ combined engine and gearbox assembly.

Something going boldly intergalactic, not a polychromatic blue dumpling with a wheel on either side.

The designers had laid their ‘power egg’ in a rolling chassis that utilised old wheels, mudguards, front forks and headlight nacelle from previous models – and it showed. If that was the best a major player like BSA could do, no wonder the UK market was going into a decline.
