The POLINI Hi-Speed variator (manufacturer reference 241.738) is an evolution stemming from competition development, designed for demanding urban scooters. Specifically designed for Kymco AK and CV3 550, it enhances the transmission behaviour for sharper acceleration and a higher rotational speed, useful in urban traffic and on fast roads.
- Concentrated performance and reliability: competition-derived design for reinforced daily use.
- Optimised transmission efficiency: better utilisation of the engine range for more responsive acceleration and pick-up.
- Special steel ring: nickel-chrome cemented, hardened and ground for increased wear resistance.
- Constant axle lubrication: maintenance of lubrication even in severe urban usage conditions.
- Reduced friction: specific treatment of the inner tracks of the rollers to limit energy losses.
- Delivered complete: variator ready to install, supplied with 1 set of 12 rollers.
Compatible notably with: KYMCO CV3 (2025 - 550 cm3), KYMCO AK 550 (2023/2024 - 550 cm3). A part intended for riders seeking a livelier and more reliable transmission for their urban scooter.
