NCY Zuma 125 Big Bore Kit

Give your Yamaha Zuma 125 some extra juice with this bolt on 158cc. Unlike most scooters, the Yamaha Zuma 125 is a Fuel Injected Scooter, and in order to get this cylinder kit to perform properly, you must purchase a Fuel Injection Module. We recommend the Polini Zuma 125 Tuner, simple plug and play option with AFR readout! Get one HERE!!
