What is a Multi-Layer Steel (MLS) head gasket?

A Multi-Layer Steel (MLS) head gasket is made of several layers of steel that work together to create a strong and durable seal between the engine block and cylinder head. This design helps prevent leaks and withstands high temperatures and pressures.

Why is the bore size and thickness important for a head gasket?

The bore size must match the cylinder's diameter to ensure a proper seal around the combustion chamber. The thickness affects the compression ratio of the engine; using the correct thickness is crucial for maintaining the intended performance and preventing engine damage.

Is this head gasket a direct replacement for the stock gasket?

Yes, this Cometic head gasket is designed as a direct replacement for the stock gasket on the specified KTM RC390 models. This means it should install without needing modifications.
