Upper chainguard
Upper chainguard for the rear drive chain, cataloged 1964-1967 under 82-5409 (formerly F5409).
This is the upper chainguard, part number 82-5409, also known under the older F5409 designation. It shows up in the parts books under the swinging fork, suspension units and chainguard figure, which places it at the rear end of the bike over the drive chain rather than up front in the primary case.

The chainguard's job is straightforward: it shields the top run of the final drive chain from mud, road grit, and the rider's leg, and it keeps flung oil and chain lube off everything behind it. Catalog appearances for this number run from 1964 to 1967, so it's tied to that stretch of production in our records.
If you're matching one up against an old parts list and see F5409 instead of 82-5409, that's the same physical guard under the earlier numbering style. Give us a call if you want to confirm it lines up with what's on your bike before you order.
