SPROCKET,A65 BSA 47T 520
47-tooth rear sprocket for the BSA A65, 520 chain pitch.
This is a 47-tooth rear sprocket listed for the BSA A65, set up for 520-pitch chain. The part number carries a Triumph-style prefix in our records, but the catalog description is plain about what it fits — this is a BSA A65 part, not a Triumph piece, so don't let the number format throw you.

We don't have much more detail on file beyond the tooth count and chain pitch. If you're sorting out final drive gearing or replacing a worn sprocket on an A65, this is worth checking against your own parts book or the wheel you're pulling it from before you order.
Give us a call if you want to confirm it's the right one for your setup — happy to talk through it before you commit.
