Polini
Description
This Polini aftermarket 13x44 up-gear set fits Yamaha Zuma 50 and bikes with Minarelli engines noted below. The set increases the top speed and lowers RPM while running full throttle. It is recommended this gear set be used after installing a big bore cylinder kit because a stock engine will not have enough power to make use of a taller gear set.
