CVT Variator Polini Hi Speed Evo 2 Piaggio

Oversize variator Polini Hi-Speed Evolution 2Variator Polini Hi Speed Evolution 2 D.14,8mm Piaggio Zip / Typhoon, for Piaggio engines with 14,8mm variator stub. This is the EVO 2, i.e. the improved version of the already very powerful Hi-Speed variator.It is an oversize model and should therefore be used with the corresponding oversize pulley, oversize rear pulley and oversize belt.The Hi Speed variators are ideal for highly tuned racing engines.Advantages of Polini Hi-Speed CVTPolini applied its extensive experience and know-how to develop a variator that delivers a clear performance boost over the stock variator, providing stable power transfer and improved acceleration across the entire RPM range. Your scooter revs more aggressively and achieves a higher top speed.The EVO 2 uses DLC (Diamond Light Carbon) bushings — lightweight, low-friction, and extremely durable. Two high-quality seals ensure consistent lubrication. The cores of the variator rollers have polished sliding surfaces, and the sleeves feature a heat- and wear-resistant Nylon/Aramid coating. The included spring with anti-torsion spring seat has +8% tension, slightly stiffer than the stock spring.Advantages of oversize CVTOversize CVT systems extend the entire transmission range and can handle much more power than standard CVTs, which primarily pays off in the upper speed range. They are therefore primarily intended for powerful engines with a lot of power at high RPM. They result in smooth shifting behavior and prevent RPM fluctuations.While oversize variators can be used with a standard pulley, optimal performance is achieved only with an oversize pulley and a longer oversize drive belt.Details Polini Hi-Speed varioVariator with ramp plateTwo sets of 6 roller weights 19x15.5 mm (3.8 and 4.3 g)Contra springEvo Slider spring seat1 tube of pulley grease

Notes and Safety Polini Hi-SpeedThe famous Polini brand lists their "Hi-Speed" CVT as part of their catalog for many years. Of course, the CVT has been upgraded and improved over time, but the basic principle is still the same: a tuning variator for original and slightly tuned engines with a noticeable increase in performance compared to the original variator.Performance Polini High Speed CVTWith newly calculated and optimized angles, the Hi-Speed variator allows an extended power band. This shows above all in noticeably better acceleration, but also in a slightly higher top speed.Two integrated O-rings provide the sleeve with better lubrication, resulting in less friction.The low-friction,
