This is a Norton part, not a Triumph part, so if you came here off a Triumph parts list, double check you've got the right catalog page. The manufacturer field on our system says Lucas but that's a mismatch with what the part actually is — Lucas doesn't make friction plates, and the description clearly points to Surflex as the maker.
We don't have more detail on this one beyond what's listed. If you're not sure how many plates your clutch stack needs or whether this matches your machine, call the shop and we'll confirm before you order.
