Cylinder kit PINASCO 75cc Sport for all Vespa PK 50 Automatica scooters. The only cylinder kit that is available for the Automatica is the one done by Pinasco. Thanks to the 47mm bore you will get a nice increase in cubic capacity to 75cc. Together with the revised port areas of the Oinasco cylinder kit you gain a very much improved acceleration as well as top speed. The power of stated as 3.8 KW and te top speed is around 70 km/h. So you have a good setup for riding with a pillion or longerdistances.
The pre-ignition should be adjusted to 18°. The delivery does not contain a new cylinder head. But thanks to the specially treated piston dome you can use the original head for the kit.
