'82 DT125 LC Piston Problem

I've just measured the bore which is supposed to be 56mm standard, but what I have here is actually 66mm.

I can't find a 10mm oversize piston, so I'm wondering if a DT175 piston will fit?

Is a DT175 piston the same length, does it have the same size pin hole, will the conrod bearing fit, are the ports the same?

Hope someone can shed some light on this.

Cheers

Chris
