NCY Yamaha Zuma125 66mm Cast Iron Cylinder w/o head. Includes cylinder only. Custom gaskets, head, and piston required.

Give your Yamaha Zuma 125 some serious power with this 198cc big bore kit. You will need to bore out the engine cases to make this cylinder kit function, which means a trip to the machine shop is in order, but seriously, will be worth it!

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:

You'll definitely want to check out our Crank Case Breather specifically for your Zuma 125. If you're adding a big-bore cylinder kit to your bike, or you ride at high RPM, this is a must-have!

Not legal for use in California on pollution controlled vehicles. Check local laws before installing.
