ATHENA offers this cylinder head gasket for KAWASAKI KX 450, KXF 450 2021-2026. The head gasket takes the pressure and heat of every combustion. It is crushed when the head is torqued down and must be replaced every time the head comes off.

Why replace this gasket every time it is removed?

The benefits:

• A new gasket guarantees a perfectly sealed joint.
• Material designed to withstand heat, oil and coolant.
• An inexpensive part that saves doing the job twice.

When should you replace the head gasket on your KAWASAKI KX 450?

Loss of compression, a dropping coolant level, bubbles in the radiator or traces between cylinder and head: the gasket needs changing. It is also replaced every time the head comes off.
