ATHENA Complete Engine Gasket Kit without oil seals for KTM GS 350, GS 500, MX 350, MX 500, SX 440, SX 500, SX 540 1986-1996

ATHENA offers this complete engine gasket kit for KTM GS 350, GS 500, MX 350, MX 500, SX 440, SX 500, SX 540 1986-1996. A full rebuild means opening the whole engine: cylinder, head, cases and covers. Every gasket removed must be replaced.

Why buy a complete engine gasket kit?

The benefits:

• One part number for the whole engine: cases, covers, cylinder and head.
• Much cheaper than buying the gaskets separately.
• Avoids the bike sitting idle for a forgotten gasket.

Why choose ATHENA?

Athena, original-equipment supplier to KTM and Ducati from Italy, laser-cuts its gaskets from materials designed for heat, oil and coolant.

When should you replace the gaskets on your KTM SX 500?

An oil or coolant leak, seepage around the cases or a loss of compression signal a tired gasket. Having the kit to hand means the bike is never stuck waiting for one missing gasket.

The manufacturer publishes no hour interval for this model: have the con-rod play checked at every piston change. Cross-Mania guideline: rebuild the bottom end every 2 to 3 top-end rebuilds.
