Gearbox sprocket - 20T
A 20-tooth gearbox sprocket, PN 57-4533, cataloged for 1973.
This is the gearbox sprocket listed in the catalog with a 20-tooth count, part number 57-4533. It shows up in the parts book under the gearbox shafts figure, which tells us where it lives in the transmission assembly but not much more beyond that.

The catalog only ties this one to a single model year, 1973, and it only turns up in one line of the parts books we have. That's a thin record, so we can't say more about exact fitment or which specific machine it was spec'd for beyond that single year.
If you're trying to match this up to your bike, give us a call and we'll go over what we've got before you order. Better to confirm than guess on a gearbox internal part.
