Norton Cotter
A cotter pin for the swinging arm spindle assembly, part number 06-4700.
This is a cotter pin used at the swinging arm spindle, part number 06-4700. The catalog places it in the swinging arm, suspension unit, and chainguard figures, so it's doing its job holding the pivot spindle secured at the back of the bike.

A cotter pin like this one is a small locking piece rather than a structural fastener. It runs through a spindle or shaft to stop a nut or pin from working loose under vibration. On a swinging arm, that pivot point takes constant motion and load, so keeping the hardware locked in place matters.
We only have this part tied to one catalog listing and it's brief, so we can't speak to specific model or year fitment beyond what's on record. If you're chasing this one down, give us a call and we'll confirm it matches your spindle before you order.
