Yes .5 and 1mm are the bore size. .50mm is .020" larger than stock bore and 1mm is .040" larger than stock. STD is standard size bore(I know, not what you'd think it'd mean, lol). If I were you I just get factory rings. Check ebay for sellers with factory rings for sale. But why rering it when you can get a decent aftermarket piston and rings. That way you know everything is new.
