1959 BSA A10
Pre-Unit 650 Twin


1959 BSA A10 Rocket

1959 BSA A10 ROCKET
By 1959, both of BSA's big non-unit twins, the 500cc A7 and the 650 cc A10 had been in production for a decade or more and had been the recipients of constant and continuous improvement. This would break and they'd make it stronger on all subsequent bikes. That would wear out, so they'd use a different part. By 1959 the BSA A10 was a well-developed bike. They were also handsome and pretty fast. The A10 Rocket was considered the top of the line with it's dual carburetors and premium trim, and the low pipes of a roadster. These were very handsome bikes, built by a powerful, swaggering BSA that was in its prime. Alas, the swagger wouldn't last. But the A10 Rocket did, because I see them all the time at shows and in auctions.

1959 BSA A10 Spitfire Scrambler

SPITFIRE SCRAMBLER
The Spitfire was indeed a 'scrambler' in the true sense of the word, with knobby tires, high pipes on the right side, one carb, and stripped of everything that wasn't essential. These are gorgeous bikes, and actually make a great off-road ride. They practically dominated desert racing in the Western US, and also many a scrambles track. The big torquey motors didn't need to be revved tight to get up hills and out of holes. Big British twins and singles ruled off-road racing around the world until the lightweight 2-strokes started pouring in from Japan and Europe.
