BSA's 1955 range embodied several novel features. Alongside the existing plunger-framed machines were new models equipped with swinging-arm rear suspension, while the A7 Shooting Star and A10 Road Rocket sports twins came with new aluminium-alloy cylinder heads. The latter produced a highly respectable 40bhp, and as tested by Motor Cycling magazine was found capable of reaching 109mph. For 1958 the sports 650 became the Super Rocket, gaining a revised cylinder head, Amal Monobloc carburettor and an extra 3bhp. This example has correct frame and engine numbers for 1962, and thus the pairing is quite likely original. The machine carries a tax disc that expired in October 1993; almost certainly not used since then, it will require re-commissioning and the customary safety checks before returning to the road. There are no documents with this Lot, which is sold strictly as viewed.
