This is an inlet valve for the BSA A10, listed for the Road Rocket and Super Rocket variants, with a 1.420 head. It's cataloged under the number 67-0968, also known by the alternate part number B135A. Despite the Triumph-style number, this one belongs on a BSA A10 twin, not a Triumph engine.

The inlet valve sits in the cylinder head and opens to let the fuel/air charge into the combustion chamber, closing again to seal the chamber on the compression and power strokes. On these older BSA twins it's a wear item worth checking whenever the head comes off, since seat condition and valve face wear affect how the engine breathes and seals.
We don't have much more detail on file for this one beyond the head size noted in the catalog listing. If you're sourcing this for a rebuild, give us a call and we'll confirm it's the right one for your particular A10 before you order.
