Athena 16-18 Kawasaki KX 450 Complete Stock Bore Cylinder Kit

If you're rebuilding the top end of your 2016-2018 Kawasaki KX 450, this complete stock bore cylinder kit from Athena is a solid choice. It's designed to bring your engine back to its original performance and reliability, ensuring you get that same smooth power delivery you expect from your bike. Athena has put a lot of thought into making sure this kit is built to last and performs like the original.

What sets this kit apart is the attention to detail in its construction. The aluminum cylinder is lightweight, which helps with heat dissipation, and it features a nickel-silicon coating on the barrel. This coating is known for its durability and low friction, working hand-in-hand with the specially designed piston to reduce wear and keep things running smoothly. You're not just getting a cylinder; this is a full package. It comes with everything you need to get the job done: the aluminum cylinder itself, a complete piston assembly with the piston pin and rings already fitted, and all the necessary gaskets to ensure a proper seal.

When you're putting this kit together, remember that it's a direct replacement for your stock cylinder. This means it fits right in without needing any modifications to your engine case. Just be aware that this kit is not CARB approved, so it cannot be shipped to California. Make sure you have all your other engine components ready for reassembly, and refer to your service manual for the specific torque values and procedures to ensure a perfect installation.
