A .040-oversize, 10.5:1 compression piston for the Triumph Tiger Cub T20.
This is a piston for the Triumph Tiger Cub, the T20, listed here at .040 oversize with a 10.5:1 compression ratio. The catalog also carries it under the older number 58-0466, which is the form you will find printed in earlier Tiger Cub parts books, so if you are cross-checking against an old book that is the number to look for.

The .040 marking tells you this piston is sized for a cylinder that has already been bored .040 over standard, so it is meant for a rebuild where the bore has been taken out that far, not for a stock-bore motor. The 10.5-1 notation is the compression ratio this piston is built to run.
We don't have more detail on this one beyond what is on the part tag. If you are matching this up to a rebore or a specific head and barrel combination, call the shop and we will confirm it is the right piston before you order.
