BSA Clutch hub
Clutch hub from the primary drive assembly, PN 40-3201, appearing in catalogs from 1969-1970.
This is the clutch hub for the primary side of the engine, the part that carries the clutch plates and locks them to the gearbox mainshaft. It's listed in the catalog under the clutch and clutch/primary cover figures, which tells you it lives inside the primary chaincase along with the chain, sprockets, and cover.

Our records show this number appearing in catalogs from 1969 to 1970, but we don't have a specific model tied to it beyond that. The manufacturer field on this one says BSA, but the description alone doesn't confirm which marque or model it actually belongs to, so before you order, check it against what's on your bike or call the shop and we'll sort out fitment together.
If you're pulling the primary cover for a clutch job, this is one of the core pieces you'll be inspecting for wear on the plate tabs and the splines that mate to the mainshaft.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
