Cupped washer
A cupped (dished) washer used in the clutch and gearbox outer cover assembly.

Our catalog record ties it to clutch and gearbox outer cover figures with appearances running 1969 through 1972, but we don't have a specific model or year pinned down beyond that range. If you're matching this up to a particular bike, check the fit against what's on the bench before you order.
The manufacturer tag on this one says Lucas, but a cupped washer in a clutch or gearbox cover isn't an electrical part, so that tag likely doesn't reflect who actually made it. Treat it as a mechanical hardware item tied to the gearbox/clutch assembly.
