For Daelim DP50E engines, you will need to take a little off the skirt. once you master that, youre golden.
For Daelim M56 engines the moped wiki states the following:
"Because of the different expansion qualities and the conductivity of the M-56 aluminum cylinder in comparison to the M-48 cast iron cylinder, the configuration of the two pistons is different. And for this same reason, the piston material is different. So both pistons are not interchangeable; and the must be separated very carefully. Only the piston rings of both the M-56 and the M-48 pistons are exactly the same. "
