    81.5 = mm.

    0.030 = inches.

    do some sae to metric conversion.

    and frankly, if you're looking at pistons for a honda sold in us measurements, i'd pass on thenm, cuz they are probably garbage or sold buy some tard cart TRYING to get in the import market and doesn't have a clue.

    Unless it comes with a set of pistons numbered 1 2 3 4 and the bores match the pistons, it wasn't bored/honed correctly. You'll have to do it again.
