What components are included in this cylinder head kit?

This kit includes the cast aluminum cylinder head, cam caps, and bolts. You will need to source valves, springs, retainers, and lifters separately to complete the assembly.

How does the design of this cylinder head improve performance?

The unshrouded combustion chamber and blended bowl design help improve airflow. Additionally, the competition-grade valve job and shortened valve guides designed for high-lift cams contribute to increased torque and power.

Are the valve seats and guides durable?

Yes, this cylinder head uses C630 nickel/aluminum valve seats and guides. This material is chosen to be easier on the valves, which helps reduce wear over time.

Product Details

This Cylinder Works cylinder head kit for your 2006-2008 Kawasaki KX250F gives you an OEM-style cast aluminum replacement head. It comes ready to install right out of the box, complete with cam caps and bolts. This kit is designed to help you get more performance from your engine.

The combustion chamber on this head is unshrouded, which helps improve airflow. It also features a blended bowl and a competition-grade valve job, meaning the ports have been carefully shaped for better performance. The shortened valve guides are made to accept high-lift cams, which can give you more torque and overall power. For durability and reduced wear on your valves, this head uses C630 nickel/aluminum valve seats and guides. The stock-shaped ports are designed to deliver high performance without drastically changing the engine's character.

Keep in mind that valves, springs, retainers, and lifters are sold separately, so you'll need to source those to complete your cylinder head assembly. This kit is a solid option for rebuilding or upgrading your KX250F's top end.
