62 x 60 bore/stroke. Not sure if you can buy rings separately but a set of new pistons/rings/pins is only $85.

Hey im confused arnt those pistons for the F8 not the f5a or are they they same?

Not sure what happened with that link, it should have gone to the F5A pistons. Their website must be a bit broken. If you search you'll find them.

They also sell genuine rings, but the price is more than the piston set! (Hope this link works!)
