50cc Polini Alu W Cylinder for Peugeot LC Mopeds
Polini 50cc "Alu W" Aluminum LC D.40.2mm Cylinder Peugeot 103 (without decompression), liquid-cooled aluminum cylinder with extremely hard chrome/Nikasil coating, delivered with HC head and 1-ring piston.
Advantages and Performance Polini Alu W
The special feature of the "W" is its W-shaped exhaust port. The main advantage of the W-shaped exhaust port is the increase in exhaust area while simultaneously protecting the piston rings. Furthermore, this mid-race / racing cylinder impresses with high material quality featuring a very resistant Nikasil coating of the cylinder bore, a high-quality 1-ring piston, and a high-compression LC cylinder head.
The performance is particularly convincing in the upper RPM range (approx. 7 hp at 9,700 rpm), and the torque is truly remarkable for a 50cc cylinder.
The cylinder should be used with a 15mm (or larger) carburetor and a suitable sport exhaust.

It is really important to combine parts that belong to the same tuning level, this is especially true for cylinders, crankshafts and exhausts.
Racing products are designed for a more extreme uses and are developed primarily for racing. Whether you stay at 50cc or increase the displacement, the corresponding Racing parts produce much higher performance than the original parts in order to achieve maximum power.
Aluminium cylinders
Aluminium cylinders are more powerful than cast iron cylinders, but require more regular maintenance and must be combined with different components such as a reinforced crankshaft and a larger carburetor.
How to run in an aluminium cylinder?
Aluminium cylinders should be run in for about 200 kilometers , and you should use a fully synthetic engine oil.
