Triumph stole a march on BSA with parallel twin architecture. The 1937 Speed Twin was such a hit that it became clear to the rival UK motorcycle manufacturers that multi-cylinder (albeit just two at present) was the future of biking.

 

And so it was that in 1946, with WW2 over, the Birmingham Small Arms Company announced the launch of the 500cc pre-unit A7. Val Page, Herbert Parker and David Munro—all greats in their field—were the design and engineering team. The A7 was initially available as a 495cc, air-cooled parallel twin, but was later reconfigured to 497cc.

 

At Sump, we've got a particular fondness for these hard-working motorcycles. They're strong, durable and solid, and yet surprisingly gentle too. A7s simply lope along effortlessly and reliably. Maximum speed is around 85mph. Economy is around 60mpg. Long distance touring is recommended.

 

In 1949, BSA enlarged the A7 brief and launched the 650cc A10. Externally, it was a very similar machine. But now, another top designer had been brought in to revise the concept. That designer was Bert Hopwood, of Norton Dominator fame.

 

By 1962, pre-unit construction (engine and gearbox as separate components) gave way to unit construction. This was the beginning of the equally worthy A65 range, and the design carried BSA along for another decade.
