This is a Norton part, not a Triumph one, so if you're working on a Commando primary and your parts book lists this number under the clutch figure, this is the centre piece the rest of the clutch stack builds around. Our catalog record on this one is thin beyond that, so if you're unsure whether it matches your particular Commando's clutch setup, give us a call before you order.
