The POLINI Hi-Speed variator (ref. 241.703) is designed for urban scooters equipped with the Kymco Downtown 300 4V engine. A specialist in transmission, Polini offers a complete steel set aimed at enhancing reliability and optimizing the primary transmission behavior without invasive modifications.

• Polini push spring: 30% stiffer than the original equipment, providing a more consistent transmission response in urban use.
• Specific variator body: internal architecture that promotes constant lubrication of the mechanism, limiting irregular stresses.
• Robust construction: delivered complete in steel and treated with nickel-chrome for better thermal stability and increased wear resistance.
• Application: intended for the Kymco Downtown 300 4V, suitable for urban journeys and the daily demands of the scooter.

This variator is aimed at riders looking for a durable and well-machined transmission part for their Downtown 300 4V. It does not promise miracles but offers a refined technical solution to improve transmission consistency and system longevity in routine use.
