Piston clip for Vespa V50, PK S, XL1, and XL2 cylinders from 50cc to 115cc (except PK 80 and PK 125).
There are two different shapes, square and round. The original Piaggio cylinder set has a square-machined locking groove. Tuning cylinders from DR, Polini, Olympia, Malossi, etc., usually have a round cutout.
The piston clips with the square shape are mounted / dismounted with a straight version of a circlip plier or this angled version of a circlip plier.
The piston clips for the round cutout are installed with a pointed plier.
