Give your Yamaha Zuma 125 some extra kick with this bolt on 158cc big bore kit. Don't forget that 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 Two Brothers Juice Box. You can purchase the juice box here on two brothers web site.
