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 speed. By replacing the variator, the scooter accelerates better, and you have a better distribution of power throughout the entire speed range. The speed will increase to 60 / 65KM/H in combination with step 1. For this variator click here.
   
   
   
3. Do you really want to maximize your scooter? Then there is also the possibility to change the Cylinder, and gear ratio of the scooter. By replacing the original cylinder with the Polini cylinder set, your compression ratio will change, thus giving you a lot more power. The cylinder displacement goes from 49.9CC to 78.8CC! The compression ratio will be 11.6:1. It is important to replace the cylinder in combination with the rear gear ratio, because you can easily run out the original gear ratio. By mounting the Polini 14/43 gear set, you increase your top speed by about 60%. By installing all the above steps, you can achieve a top speed between 80 / 90KM/H!
