Reed valve -POLINI Evolution- Minarelli 50cc (vertical cylinder) – BOOSTER, BUMP50, BWS50, SLIDER50, SPY, SR50 (-1994), STUNT, ZUMA50, AMICO offerta

Description

The Polini Evolution reed valve block offers a larger intake area and therefore contributes to a better cylinder filling. The intake angle is flow optimized on the PC to ensure a perfect flow of the mixture.
The surface of the reed block is vulcanized and so the carbon plates seal perfectly and provide a perfect pressure balance in the crankcase.
