DR Piston (63.4 mm, 1st Oversize) for Vespa P/PX, Stella

Replacement Piston for Vespa P/PX and Stella

This first oversize piston is made for the DCK2 cylinder kit, which is used on P125 models and Stella scooters. Correct piston sizing plays a key role in keeping the engine running well. As one of the vintage Vespa scooter parts, it suits restoration work. The package comes with a wrist pin, circlips, and rings so you have everything needed for a full replacement.

What This Part Does

The piston and rings work together to seal the combustion chamber. When the rings start to wear, you might notice smoke, higher oil use, and lower compression. Make sure the piston diameter and oversize size match your cylinder for the best results.
