ATHENA complete engine gasket kit for HUSQVARNA FC 450, KTM SX-F 450 and GAS GAS EX 450 F from 2019 to 2023

ATHENA offers this complete engine gasket kit for HUSQVARNA FC 450, KTM SX-F 450 and GAS GAS EX 450 F from 2019 to 2023. 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?

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.

Recommended hours for a bottom-end rebuild (manufacturer recommendation for the KTM SX-F, Husqvarna FC 2016-2022):

• Racing: every 100 h.
• Leisure: no KTM figure; have the wear checked at every top-end rebuild.
• KTM EXC-F, Husqvarna FE 2017-2023: racing: every 70 h.
