Additionally, this cylinder head comes with a new set of valves and valve seats, which offer improved flow and reduced friction, resulting in a smoother engine operation. The valves are manufactured using a high-temperature, wear-resistant material, ensuring their longevity under the rigors of off-road riding.

The BFO LG9K8T 70cc Cylinder Head is designed to be a direct replacement for the stock cylinder head on Honda ATVs. It is engineered to meet OEM specifications, ensuring a perfect fit and seamless integration into the engine.

In summary, the BFO LG9K8T 70cc Cylinder Head is a high-performance upgrade for Honda CRF70, CT70, C70, TRX70, and XR70 ATVs.
