Description

Kawasaki OEM Part 11004-0805: Cylinder Head Gasket

Part number 11004-0805 (also listed as 11004-0805) is a genuine Kawasaki OEM cylinder head gasket, commonly referred to as “GASKET-HEAD.” It is a critical sealing component that sits between the cylinder head and the engine block (or cylinder), preventing leakage of combustion gases, oil, and coolant while maintaining proper compression.

This part supersedes the earlier number 11004-0774. It is sold as a brand-new, factory-original Kawasaki component and is typically priced in the range of $65.00/$70.00 USD  . Availability is Always in stock @ Spears Racing .

The gasket is compatible with a range of recent Kawasaki street and off-road models. Documented applications include:

• Ninja 400 (various 2018–2023 and later variants, e.g., EX400 series)
• Eliminator 500 and Eliminator 500 SE (2024 models, EL450 series)
• KX250 (select years, including EX400/EX500 designations)
• Ninja 500 and related  Z500 / Z500 SE  models (2024)

As an OEM part, 11004-0805 is manufactured to Kawasaki’s exact specifications for material, thickness, and sealing surfaces. Using the genuine gasket is recommended during top-end rebuilds, head removal for valve service, or any work that breaks the head-to-cylinder seal, because aftermarket alternatives may not match the precise dimensions or multi-layer construction required for reliable sealing under modern engine temperatures and pressures.

In summary, Kawasaki 11004-0805 is the current genuine cylinder-head gasket for a family of popular 400–500 cc Kawasaki motorcycles. It is a direct-fit, high-quality sealing part essential for maintaining engine integrity after cylinder-head service. Always verify fitment against the specific model year and chassis number before purchase, as Kawasaki occasionally updates part numbers across production runs.
