Camshaft pinion
A camshaft timing pinion for the crankshaft/connecting-rod assembly, PN 71-2719 (also listed as E12719).
71-2719 is a camshaft pinion listed in the Triumph parts books under the CRANKSHAFT AND CONNECTING RODS figure, with the legacy alias E12719 for anyone working from an older book. It's a timing gear that rides on the camshaft, meshing with its mating gear off the crankshaft to keep valve timing synced to piston position.

Our catalog record for this one is thin, just the single listing, so we don't have extra detail on dimensions or which specific engine family it was cut for beyond what the figure title tells us. If you're matching this against a bike, bring in the old part or your parts book number and we'll confirm before you order.
Gears like this wear at the tooth face and the bore over time, so if you're pulling one for inspection it's worth checking both while the timing chest is open.
