I took off the top end of mine when I first got it to change the head studs and head gasket.
The gasket that I put in was the standard 66cc one from SBP. It was not a larger bore. The piston in the photo looks considerably larger in diameter than a stock 66cc.
It is possible that their scam is just taking a picture of a piston from some other 2 stroke engine and claiming it is theirs.
