Reproduction of the wide wall cylinder with 50 cc displacement and narrow exhaust for your Pony moped / moped with Sachs 503 AB, AC or ADV engine.
The ports, timing and appearance are almost identical to the original. The replacement cylinder also has a bore for the deco valve.
In addition to the piston, piston ring, clips and bolts, the scope of delivery also includes the required gaskets for the base, intake and exhaust. In addition, an O-ring and a reinforced graphite gasket for the cylinder cover are included, which can be used as required. It is still possible to use the original cylinder head.

Capacity: 49.90 cm³
Ø Cylinder neck: 52 / 50.5 mm
