BSA CHAIN GRD,A65 BARE 68-70
Bare, unfinished rear chainguard for the BSA A65, catalog PN 82-9192 (alias BCS13).
This is a bare rear chainguard for the BSA A65, part number 82-9192, also known by the older reference BCS13. It's unfinished metal as it comes from the shop, so plan on paint or plating before it goes on the bike. The catalog places it with the rear mudguard and chainguard assembly, where it covers the top run of the final drive chain to keep road grime and chain oil off the rider's leg and off the chain itself.

The catalog ties this one to the A65 across 1969 and 1970 appearances. Other catalog listings for this same guard also mention an A50/A65 version with a mounting bracket, so if your bike needs the bracketed style, check which one you're ordering before it ships.
Since this is a BSA part and not a Triumph, it's not something to reach for on a Triumph twin even though it lives in the same primary/chainguard family of parts on the shelf here. Confirm the guard matches your frame and mudguard mounts before bolting it up.
