G'day from Australia, A10 Super Rocket has a single R stamped in the engine numbers and a Road Rocket has RR in the engine numbers, no Rs then it's an A10, hope that helps, cheers mate.
Sorry but this BSA isn't from 1960. as the sign posted indicates. Ventiladed dual-shoe frente system brake, came on later models. Beautiful bike!!!! Thanks Andy for sharing!!!
You don't date a bike by the parts that have been fitted by previous owners , like the later and better brake . You date it by the frame number , and this one is 1960 .
i have the Super Rocket with the high compression pistons , got to get the advance retard lever right , if you don't , it kicks back like hell .. this bike looks more friendly .. give an A10 over a Bonnie any day .
