Athena 21-24 Kawasaki KX 250 F 78mm Bore 250cc Stock Bore Complete Cylinder Kit

The nickel-silicon coating on the barrel of this Athena cylinder is a key detail that helps reduce friction and improve durability. This is a complete cylinder kit designed to match the performance of your original Kawasaki KX 250 F engine, offering a reliable way to rebuild or replace your stock cylinder. It’s built for riders who need their bike to perform consistently, whether on the track or trail.

Athena uses a lightweight aluminum cylinder in this kit, which helps with heat dissipation and keeps overall engine weight down. The piston is specifically designed to further minimize friction, contributing to smoother operation and potentially improved responsiveness. This attention to detail in materials and design means you're getting a well-built component that aims to restore your engine's original power and reliability.

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 ensure a proper seal. This comprehensive approach means you won't be scrambling for extra parts during installation. Just remember that this kit is not CARB approved, so it cannot be shipped to California.
