ATHENA complete engine gasket kit for KTM SX 125, SX 150, HUSQVARNA TC 125, TE 150 and GAS GAS MC 125 from 2016 to 2023

ATHENA offers this complete engine gasket kit for KTM SX 125, SX 150, HUSQVARNA TC 125, TE 150 and GAS GAS MC 125 from 2016 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, Husqvarna TC 125-300 2017-2022):

• Racing: every 40 h.
• Leisure: no KTM figure; have the wear checked at every top-end rebuild.
• KTM EXC 150 TPI, Husqvarna TE 150i 2020-2023: racing: every 40 h.
