Steel is right, first oversize has "50" on the piston, sometimes underneath another number. Second oversize has "100" on the piston.

562cc.kz500 =[55.0*52.4]mm bore and stroke [standard]
kz550 =[58.0*52.4]mm bore and stroke [standard]
First oversize @0.5mm gives
[58.5*52.4]mm
The kz500 = 497cc
The kz550 = 553cc
So 3mm on the bore =56cc
So 0.5mm on the bore = [1/6] *56 = about 9.4cc
So 553 + 9.4 = about 562cc.:blink:
