The year of 1963 marked the end of production for one of the best and rarest of all the BSAs - the Super Rocket. For many, this signaled the final stage of development of the fabulous BSA A10 twins and the end of the pre-unit era. Made specifically for the American rider, the Super Rocket was a tuned A10 motor that offered a new order of high-performance speed. With generous amounts of chrome, polished alloy and deep enamel, the 1963 Super Rocket marked the very best of the end of an era. Priced at US $1,200, the only machine produced by BSA that was more valuable was the Rocket Gold Star. The 1963 model offered forks, brakes and wheels from the impeccable Gold Star. Add to this alloy heads, streamlined inlet ports, racing valve springs, a crankshaft drive supported by special high-duty variable valve springs, oversized inlet valves, a '357' full-race camshaft, an improved free-flow exhaust system and a 1 5/32  Amal monobloc carburettor with a large capacity air cleaner and you had a very capable motorcycle. In the bottom end, BSA clipped on a four-speed gearbox with new quick acceleration gear ratios, and a new power jet exhaust system for a better extractor effect (to lessen back pressure) and increased horsepower. Overall, the Super Rocket was, and remains, one of the great swansongs of the British motorcycle industry.
