ATHENA Cylinder Base Gasket for HUSQVARNA 701, KTM ENDURO 690 and GAS GAS ES 700 2017-2024

On KTM ENDURO 690, HUSQVARNA 701 and GAS GAS ES 700 from 2017 to 2024, the ATHENA S410270006158 cylinder base gasket fits in place of the original part. Fitted under the cylinder, the base gasket is more than just a seal: its thickness sets the height of the cylinder, and with it the engine's squish and compression.

Key features

• Several thicknesses available for the same bike.
• The right tool for setting squish, compression and timing, according to Athena.

Fitting tips

1. Clean the crankcase face and the base of the cylinder without scratching them.
2. Fit the gasket dry, centred on the studs.
3. Tighten the cylinder in a criss-cross pattern to the manufacturer's torque.
4. If you have changed the thickness, measure the squish before refitting the cylinder head with a new head gasket.
