Cylinder Polini Alu W for Peugeot 103
Cylinder Polini 50cc "Alu W" D.40mm Peugeot 103 AC (without head), powerful aluminum cylinder with extraordinary "W"-shaped exhaust.
Performance and characteristics Polini Alu W
The power really shines at high RPMs (around 5–6 HP at 9,300 rpm), while the torque is impressive for a 50cc cylinder. The standout feature of the "W" is its W-shaped exhaust port.
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.
