75 cc racing cylinder from Polini for Vespa V50 and PK50

The 75cc Polini Racing is, just like the D.R. 10-channel, a very sporty cylinder. Here, 6 overflows are responsible for a powerful scavenging of the cylinder. The coated piston is just as obligatory here as the two additional pre-exhaust ports.

The cylinder responds well to a LeoVinci exhaust and larger carburettors.

Super petrol should also be used here due to the higher compression ratio of 1:11.9. Polini specifies a top speed of 90 km/h, but achieving this requires a well-practiced mechanic's hand.
This is how we ensure, that reviews come from real consumers.
