BSA A10 Parts & Spares
The 646cc A10 is the pre-unit BSA twin that most people picture when the marque comes up: a long-serving, unfussy engine in a separate gearbox chassis, sold as everything from a plodding Golden Flash to the Rocket Gold Star. Thirteen years of production left a lot of variation behind the shared model name.
Obsolete Bike Parts holds getting on for a hundred A10 items, including the pre-unit specific cases, covers and mountings that the later unit twins do not share. Where original stock has run dry we list reproduction we have handled ourselves, and we ship anywhere.

Which A10, and which frame?
The engine ran through the fifties and into the early sixties, and the chassis under it changed more than the motor did: rigid and plunger frames early on, swinging-arm frames later. Tuned versions followed the standard Golden Flash, the Road Rocket first and then the Super Rocket and the Rocket Gold Star, each with its own head, carburation and finish. A frame number tells us which chassis parts you need and an engine number tells us the rest.

Mixed-up machine?
Plenty of A10s have collected parts from several years, and a few have collected them from the A7 as well. Photograph what is actually fitted, tell us what the bike is being built for, and we will work from that rather than from the catalogue page the model name points at.
