One good idea is to measure the piston and measure the cylinder.

A bore gauge will tell you what boe size you have....and then a parts man/woman should be able to tell you what piston you need.

Do you have the jug(s) off already?

Or at least the head(s) ?

you need a micrometer or a Caliper

a caliper would probable be cheaper, but make sure it go's within a thousandths (.000mm) happy rebiulding

You already have the piston out. Take the cylinder to a shop and have them put a bore guage in it. Then you'll know what piston you need.

If this is an OEM Honda Piston and there is not a marking on the top of the piston, then it is the original bore size.

As per Redbeard, Take the CYLINDER to the dealer / machinist, have them measure that to determine whether or not a larger diameter piston is required.

Well if im asking here is becuase i want buy the piston online since in USA is cheaper.

Otherwise i wouldtn mind to go to a shop and make them charge extra for this simple question instead of doing myself and buying directly online.
