BSA SPROCKET,21T FOR A10 SRM
A 21-tooth sprocket for the BSA A10, listed under an SRM part number.
This is a 21-tooth sprocket listed for the BSA A10, referenced here under an SRM part number. BSA made the A10 - a Rocket, Golden Flash, or similar A10-family machine - and this is not a Triumph part despite what the manufacturer tag on our system might suggest; the catalog description is plain about it being BSA fitment.

Our record on this one is brief - a tooth count and the model it's built for, nothing more on dimensions, bore, or which shaft it mounts to. If you're sorting out gearing or a chain conversion on an A10, give the shop a call and we'll confirm the specifics before you order.
