This kit will fit on all Primavera and ET3 scooters, and also post-1965 Vespa 90. Additionally, it will fit on some Vespa 50's, but we recommend upgrading your gearing on 50cc engines at the same time. You will need four long cylinder studs and a Primavera shroud to use on these models.
This will not fit on '63-64 model Vespa 90 (small door models). Sorry; no cylinder kit will!
Performance upgrades are considered racing parts and are not covered by warranty. There are too many variables involved with user-installed parts, and pushing the limits of your engine tends to wear parts faster. Use at your own risk!
Replacement rings can be ordered here.
Looking for more performance upgrades? We also carry a Primavera high performance kit that inlcludes this cylinder!
