VALVE NORTON EXHAUST KWPM
Norton exhaust valve, catalog number 065115R (also listed as 50-4091).
This is an exhaust valve for a Norton, not a Triumph part. Our catalog picked it up under the number 065115R, with the older reference 50-4091 also tied to the same physical part. The description on file just calls it out plainly as a Norton exhaust valve, so that's what we can tell you with confidence.

We don't have detailed fitment notes, dimensions, or material specs on file for this one. If you're chasing this for a specific Norton engine, give the shop a call and we'll help confirm before you order.
Worth keeping in mind this one shows up rarely in our records, so we're going off the base catalog listing rather than a long history of notes on it.
