NCY Zuma125 59mm aluminum cylinder with a cast iron sleeve w/o head.

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 should purchase a Fuel Injection Module.

We recommend the Two Brothers Juice Box. You can purchase the juice box here.

 This is a high-flow crank case breather for your Zuma 125 made of billet aluminum from NCY.

This is a must-have for big bore cylinder kits, or for extended high-rpm running! Even with regular riding around town, some of the compression in your cylinder slips past the piston rings and builds up in your crank case. When you ride at high RPM, or when you add a big-bore cylinder kit, all that pressure builds up much faster and can easily blow out the seals on your crank case. Save the seals!

This unit bolts on just over your cam sprocket, where there is currently a plug. After bolting it on, just run a breather tube (not included) up under your seat or back to your airbox.
