Norton Sprocket with Backplate
Norton Commando clutch sprocket with backplate, part of the primary chainwheel assembly.
This is a Norton Commando part, not a Triumph piece, so if you're wrenching on a Triumph this one isn't for you. The catalog lists it as a sprocket with backplate that lives in the clutch assembly, on the primary side of the engine.

The sprocket and backplate work together as the driven half of the primary chain setup, carrying power from the engine sprocket back through the chain into the clutch basket. Our record only ties this part to a single catalog year, so if you're chasing exact fitment for your machine, give us a call and we'll sort out whether it matches what you've got.
We don't have much more detail on this one beyond what's in the clutch figure. If you're not sure this is the right part for your Commando, best to check with us before ordering.
