SYM 50cc Cylinder Kit

50cc Cylinder Kit for SYM and Peugeot Scooters

This cylinder kit is built to replace the cylinder assembly on a range of SYM and Peugeot four-stroke 50cc scooters. The package contains the cylinder, piston, ring set, wrist pin, retaining clips, and gaskets. It sits among our scooter big bore and cylinder kits and works for both repair work and replacement jobs. Installed correctly, it helps your scooter run smoothly and reliably, which makes it a useful item to keep on hand for routine maintenance.

Components Included

You receive one cylinder, one piston, a complete ring set, a wrist pin, retaining clips, and gaskets for the cylinder head, base, exhaust, and cam chain tensioner. The parts are made to match SYM and Peugeot scooters so they fit and work with the existing engine systems during installation.

Installation Guidelines

Swapping out the cylinder kit is a manageable task for anyone with basic mechanical experience. Take off the old cylinder, fit the new one, and check that every gasket sits in its correct position to avoid leaks. The kit covers several models, so it suits owners who want to carry out their own repairs.
