Do you want to upgrade your Piaggio Zip, Vespa Primavera, Vespa Sprint or Piaggio Liberty model? Then follow the steps below:

1. Replace your current ECU with this Polini ECU. The original ECU of your scooter is limited to 8000RPM. By mounting the Polini ECU, you can achieve a speed of 9600RPM. This increases the speed of your scooter from 45KM/H to about 55KM/H. For this ECU click here.
   
   
   
2. Replace your original variator with the Polini High Speed variator. The Polini High Speed variator ensures that the power of your scooter is better distributed at every RPM. By replacing the variator, the scooter accelerates better, and you have a better distribution of power throughout the entire RPM range. The speed will be increased to 60 / 65KM/H in combination with step 1. For this variator click here.
   
   
   
3. Do you really want to maximize your scooter's performance? Then there is also the possibility to change the Cylinder, and gearing of the scooter. By replacing the original cylinder with the Polini cylinder set, your compression ratio will change, and you will get a lot more power. The cylinder capacity goes from 49.9CC to 78.8CC! The compression ratio is now 11.6:1. It is important to replace the cylinder in combination with the rear gearing, because you can easily outperform the original gearing. By mounting the Polini 14/43 gearing, you increase your top speed by about 60%. By mounting all of the above steps, you can reach a top speed between 80 / 90KM/H!. For the cylinder set click here.
