CYLINDER WORKS CH1003-K01 High-Performance Cylinder Head Kit for Honda CRF250R & X (2004-2007)

Upgrade your Honda CRF250R or CRF250X with the CYLINDER WORKS CH1003-K01 high-performance cylinder head kit. Designed specifically for models from 2004 to 2007, this replacement cylinder head offers significant improvements in power, efficiency, and durability. Crafted with precision and attention to detail, this kit is ideal for riders seeking to enhance their motocross or off-road performance.

The kit features a brand new replacement cylinder head that includes essential components for a comprehensive upgrade. It comes with cam caps and cam cap bolts, ensuring proper assembly and secure fit. The inclusion of C630 (nickel/aluminum/bronze) valve seats and guides guarantees long-lasting valve operation and resistance to wear, which is critical in high-performance applications.

One of the standout features is the competition valve job, which optimizes airflow and combustion efficiency. The shortened valve guides accommodate higher lift cams, allowing for increased airflow and power output. The unshrouded combustion chamber and blended bowl design improve combustion efficiency, contributing to better throttle response and increased horsepower. Additionally, the stock-shaped ports maintain a familiar flow path while benefiting from the enhancements made during manufacturing.

It's important to note that this cylinder head kit does not include valves, springs, or lifters; these components need to be sourced separately. Its lightweight design, combined with the high-quality materials used, makes it an excellent choice for competitive racing or serious off-road riding. Whether you're rebuilding your engine or looking for a performance upgrade, the CYLINDER WORKS CH1003-K01 kit delivers quality and performance tailored for demanding riding conditions.
