The Polini Maxi Hi-Speed variator part number 241.777 has been developed to improve the transmission performance of the new Kymco Agility S 125 Euro 5 Plus and Kymco Skytown 125 Euro 5 Plus equipped with the TH25 engine.
Designed for everyday scooter riders, the Maxi Hi-Speed provides quicker acceleration response, smoother recovery and more linear power delivery during speed changes typically experienced in urban riding.
The complete transmission kit is engineered for fast replacement of the original variator while improving overall scooter performance without compromising reliability or riding comfort.
The specially designed movable pulley half allows greater belt travel, ensuring smoother and more progressive acceleration.
The contrast spring with 10% increased stiffness compared to the original helps maintain more stable engine RPM during launches and acceleration.
Rollers coated with nylon and aramid fibers reduce friction and wear, ensuring long-lasting and consistent performance.
