I have a Wiseco piston that was in a bunch of Sachs stuff.It is marked Special on the box and has a #PS210.It is a flat top single ring with the pin at the 10 oclock position towards the arrow on the crown.I am guessing about 58mm in diameter.Good luck!
Hi,
According to my Wiseco chart a 210PS should be a standard bore Carabella 125 measuring 55.4 mm. Wiseco shows it as a double ring piston though so guess it's still a mystery.

While back I purchased a batch of Wiseco Pistons and come to find out that many of the Pistons were not in the correct boxes.?!?!?!
