Malossi, Cylinder Kit (132.4cc); Vespa Primavera Buddy 125 Performance the Blue Line version featuresThis cast iron kit is set up for more power in the higher RPMs, at the expense of a little bottom end and midrange power. Extremely high quality Malossi is known for! A recommended carburation upgrade is the Malossi reed valve kit. We also recommend the Polini exhaust. 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
