ATHENA Cylinder Head Gasket for HUSQVARNA 701, KTM ENDURO 690 and GAS GAS ES 700 2017-2027

The ATHENA S410270001061 head gasket is designed for KTM ENDURO 690, HUSQVARNA 701 and GAS GAS ES 700 from 2017 to 2027. The head gasket seals between the cylinder head and the cylinder: it holds in the combustion pressure and, depending on the engine, the coolant. Crushed when tightened, it can never be reused.

Fitting tips

1. Clean the cylinder head and cylinder faces without scratching them.
2. Fit the gasket dry, the right way round, centred on the studs and the coolant holes.
3. No sealant on the gasket.
4. Tighten the cylinder head in a criss-cross pattern, in several stages, to the manufacturer's torque.
5. Refill the coolant and take the opportunity to replace the spark plug.

Frequently asked questions

Is the gasket enough to refit the cylinder head?
It replaces the head gasket only. If you also remove the cylinder, go for a complete top end gasket kit instead.
