Browse compatible alternatives125cc Piaggio cylinder kit by SIP for Vespa PX80 /PX100 scooters.
SIP have produced a range of cylinder kits modified to fit older engine types where the cylinders are no longer produced. With this kit SIP have taken a Piaggio original PX125 cylinder and turned the cylinder base down to fit 80cc crankcases.
The original 80cc crankshaft will need to be replaced with a PX125/150 crankshaft with a 57mm stroke. Longer transmission or a 21-22 teeth clutch cog is recommended.
