OIL RING .010 T150
A .010-over oil control ring for the Triumph T150 Trident piston.
This is an oil control ring listed as .010 over standard bore, catalogued for the T150 Trident triple. Oil rings sit in the lowest groove of the piston and scrape excess oil off the cylinder wall on the downstroke so it drains back to the sump instead of getting burned in the combustion chamber.

The .010 marking tells you this ring is sized for a cylinder that's been bored .010 over stock, so it's meant to go with a matching oversize piston, not a standard-bore rebuild. We don't have much more written down on this one beyond the catalog listing itself.
If you're doing ring work on a Trident top end, give us a call to confirm this is the size you need before you order — best to have your bore measurement in hand.
