Overview[edit | edit source]
BSA Super Rocket (A10)
The Super Rocket has a near-three-figure cruising speed a performance to meet the autobahn ambitions of foreign-touring enthusiasts, or those who buy motorcycles with an optimistic eye to the extension of motorway travel at home in the not too distant future. On the other hand, the current model can be throttled back to accept happily the inevitable limitations of built-up-area riding. In these less spectacular circumstances, one's patience in jogging along at 30mph is rewarded by a remarkable - for a lusty 650cc twin - fuel consumption also in the three-figure class.' - Motor Cycling.
BSA's range for 1955 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 aluminum-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 carburetor and an extra 3bhp. The model lasted into the unitary construction era and was last produced in 1963.
