The A10 had a reputation
for reliability but was struggling to compete against the Triumph engines and
the Norton Featherbed frames. Advertised by BSA in 1954 as 'undoubtedly the
worlds greatest motorcycle' the Road Rocket was discontinued in 1958 when it was
replaced by the BSA Super Rocket.
Launched as the top of BSA's range in 1954 the BSA Road Rocket had an A10 engine
with an alloy cylinder head, high compression pistons and a high lift camshaft,
giving 40 bhp (30 kW) and a top speed of 109 mph (175 km/h).
