Big bore kits are unrivalled for increasing power and torque on your scooter engine. Malossi is Italy's famed racing parts manufacturer and designer, and a favourite cylinder maker of ours. Their cylinders are durable and quite underrated when it comes to acceleration and high RPM performance.
To suit 2 stroke horizontal, air cooled Piaggio engines including:
Zip 50cc 2 stroke (all)
Vespa Sprint/Primavera 50 (Auto)
Vespa LX50, LXV 50 (2 stroke only)
Liberty 50cc 2 stroke
As well as Aprilia and Gilera 50cc air cooled horizontal 2 stroke engines using the Piaggio engine (including Ice, Typhoon 50, Sport City 50, SR50 Motard). Kit includes cylinder, piston, gaskets, piston rings, gudgeon pin, small end bearing, reed petals and clips.

This kit must be fitted and the carb tuned by a technician or skilled person. Piston seizure is a symptom of poor carburetor tuning and claims regarding these kinds of problems will not be accepted. This increases engine size so that your bike may not be legally registered as a moped.
