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

PROX offers this complete engine gasket kit for KTM SX 125, SX 150, XC-W 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 PROX?

ProX, the Dutch engine-parts specialist since 1975, has its parts made in factories that also supply the manufacturers: OEM quality at a more affordable price.

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):
