BSA Silencer
A 1971-catalog silencer with a bare listing — call to confirm exact fitment before ordering.
This is a silencer, listed once in the catalog under the TWINSEAT — CHAINGUARD — SILENCER figure grouping for the 1971 model year. That figure title tells us it sits with the seat and chainguard parts in the parts book layout, which is a common way exhaust and body-adjacent components got grouped on the page, but it doesn't give us a specific model or engine size to point to.

The manufacturer tag on this one says BSA, which is worth a flag rather than a fact — the description is just "Silencer" with no model name attached, so we can't confirm which marque or machine this piece was built for from what's in front of us.
Given how thin the record is here, the safest move is to call the shop with your frame or engine number in hand. We can cross-check against what else turns up for 1971 and get you the right part instead of guessing off a bare listing.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
