Serrated washer
A serrated washer (82-5299 / F5299) used in the ignition capacitor and T100C headlamp fitting area.
This is a serrated washer, catalog number 82-5299, also known by its earlier alias F5299. It shows up in the parts book under the ignition capacitor and T100C headlamp figure, so it's a small hardware item used to secure a fitting in that area rather than a structural engine part.

Serrated washers like this one bite into the mating surface to help keep a nut or fastener from working loose, which matters on a fitting near the headlamp shell or capacitor mount that sees vibration. Our catalog record for this one is thin - it only turns up in a single listing tied to 1969 - so we can't speak to broader fitment beyond that.
If you're chasing this part number down, have your parts book open to the same figure to confirm you're looking at the right washer position before you order. Call the shop if you want us to double check against your bike.
