What does a top end gasket kit include?

A top end gasket kit typically includes all the gaskets needed to reseal the cylinder head and cylinder to the engine block. This ensures a proper seal for combustion and coolant/oil passages.

Why is surface treatment important for gaskets?

Surface treatments help compensate for minor imperfections on the mating surfaces of the engine components. This allows the gasket to create a more reliable and leak-free seal, especially under high pressure or temperature.

Are these gaskets made to OEM specs?

Yes, Athena produces these gasket kits following strict parameters set by the original equipment manufacturers, ensuring they meet the same standards as the parts your KTM came with.
