Cylinder Works 2008 CRF 250 R Cylinder Head Kit

This Cylinder Works cylinder head kit for your 2008 Honda CRF250R comes with everything you need to get your engine back in top shape. You'll find the cast aluminum cylinder head itself, along with the necessary cam caps and bolts, all ready for installation right out of the box. This kit is designed as an OEM-style replacement, meaning it's built to fit and function like the original, but with some notable improvements for better performance.

The combustion chamber in this head has been unshrouded to help improve airflow, and it features a blended bowl with a competition-grade valve job. This means the engine can breathe more freely, leading to increased torque and power. The valve guides have been shortened to accommodate high-lift cams, which further contributes to enhanced power output. For durability, it uses C630 nickel/aluminum valve seats and guides, which are gentler on the valves themselves, helping to reduce wear over time. The ports are shaped to stock specifications, ensuring high performance while maintaining compatibility.

Keep in mind that while this kit includes the cylinder head, cam caps, and bolts, you will need to purchase the valves, springs, retainers, and lifters separately to complete the assembly. This approach allows you to select the exact valvetrain components that best suit your riding style and performance goals.
