Cylinder Polini 210 cc race in aluminum 57 for Vespa 200

Polini Aluminium 7 ports cylinder, bore Ø 68.5, stroke 57mm for Vespa PX/PE 200 - Rally 200 (head included) THESE COMPONENTS ARE FOR RACING-SPORT USE ONLY There were three choices on the market: The Pinasco 215 known for its great reliability and low torque, the Malossi 210 famous for its high power at high revs and the cast iron Polini 208 known for being the most harmonious cylinder in terms of low torque and high performance, probably the most enjoyable of the three but with low reliability if not set correctly. The new 208 Polini in aluminium retains the same conformation of the transfers, the 68.5 mm diameter piston with first L-shaped piston ring. In short, those who have the engine ready for the cast iron 208 can replace the cylinder immediately without making any modifications! The reliability of the aluminium cylinder is beyond question, so the Polini 208 will guarantee great performance and reliability to the most demanding Vespisti.
