Athena 17-19 Kawasaki KX 250 F 77mm Bore 250cc Stock Bore Complete Cylinder Kit

The nickel-silicon coating on the barrel of this Athena cylinder kit is a key detail that helps manage heat and wear. This is a complete cylinder kit designed to bring your 2017-2019 Kawasaki KX 250 F back to its original performance specifications. When you're rebuilding the top end of your engine, getting the cylinder right is crucial for smooth operation and reliable power delivery.

Athena developed this kit using a lightweight aluminum cylinder, which helps with heat dissipation compared to heavier cast iron options. The piston is specifically designed to reduce friction, working in tandem with the coated barrel to ensure the engine runs as efficiently as possible. This kit aims for extreme reliability, meaning you can trust it to perform consistently. It's built to match the performance you'd expect from original spare parts, giving you that familiar feel and power.

When you open the box, you'll find everything you need to get the job done: the standard bore aluminum cylinder, a complete piston assembly including the piston pin and rings, and all the necessary gaskets to seal everything up properly. This makes it a straightforward replacement for your worn-out cylinder, ensuring a solid rebuild.
