Cylinder Polini W 65cc Peugeot 103
Polini Big Bore "Alu W" Peugeot 103 AC cylinder, aluminum cylinder with extremely hard chrome/Nikasil coating, supplied with 1-ring piston.
The performance is particularly impressive in the upper RPM range (approx. 7.3 hp at 8000 rpm), the torque is really impressive for a 65cc cylinder. The special feature of the "W" is its W-shaped exhaust.
The cylinder should be run with a 15mm (or larger) carburetor and a suitable sports exhaust. The original cylinder head can be used, but we recommend a high-compression head to achieve a little more power.

Tuning Level: Racing
We categorize our products into different performance levels Original, Sport, Racing and High End , so that our customers can choose the right parts for their setup. 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.

Aluminium cylinders should be run in for about 200 kilometers , and you should use a fully synthetic engine oil.
