Athena CPI Popcorn 50 40mm Bore 50cc Standard Bore Cylinder Kit w/out Head

This is the Athena CPI Popcorn 50 standard bore cylinder kit, designed for 50cc applications with a 40mm bore. It's built to match the original performance of your 50cc engine, offering reliable operation and a smooth running experience. If you're looking to replace a worn-out cylinder or rebuild the top end of your small displacement scooter, this kit is a solid option.

The cylinder itself is made from lightweight aluminum, which helps with heat dissipation. Inside, you'll find a barrel treated with a nickel-silicon coating for durability, and the included piston is designed to minimize friction, contributing to better efficiency and a longer lifespan. This kit comes with everything you need to get the cylinder installed: the aluminum cylinder, a complete piston assembly with pin and rings, and all the necessary gaskets.
