Description

The Polini Performance Variator Kit is widely regarded as the gold standard CVT upgrade for the pre-2022 Yamaha Zuma 125 (BW/BWS 125) and Yamaha Cygnus 125. Its larger-diameter variator pulley unlocks higher top-end speed while delivering smoother, more consistent acceleration throughout the RPM range — a meaningful upgrade over the stock unit for any serious Zuma rider. Made in Italy by Polini, a name synonymous with performance since 1951. SKU: 1200-1217.
