Default Re: Can someone tell me the diameter of a 66 piston head?

Thank you

or 117.5% of surface volume of the 50cc piston.

So it stands to reason, if the stroke is still the same- and boygofast at least seems to be advertising the same bottom end for both engines- at least with 6mm studs-

the 66cc is 117.5 percent larger than the 50cc, or then actually 58.75 cc?
What am I missing here?
