Cylinder Head Gasket
A cylinder head gasket is high-effort to replace and a sealing failure can cause severe engine damage; the genuine Japan-made Yamaha gasket provides the highest confidence in correct thickness, materials, and long-term sealing, which outweighs the limited value advantage of most aftermarket options for this job.

Genuine Yamaha Japan-made gasket with a composite sealing body and properly formed metal fire rings around all three cylinders for high-pressure combustion sealing. The precise OEM die-cut oil/coolant passages and controlled thickness/material spec make it the lowest-risk choice for a labor-intensive head gasket replacement.
