Reed valve pack PoliniCode: 213.0036The Polini valve or reed valve regulates the flow rate of fresh gases in the combustion chamber of 2-stroke engines. The extremely precise construction of the Polini reed valve packs allows a better intake allowing an improvement of the gas flows inside the combustion chamber of the engine with a significant increase in the vehicle's performance over the entire delivery curve and a better thrust at all revs. The particular design and use of materials make this reed valve more resistant and durable than the OEM equivalent.
