INNTECK Complete Engine Gasket Kit for KTM EXC 125, SX 125 1991-1997

INNTECK offers this complete engine gasket kit for KTM EXC 125, SX 125 1991-1997. 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 INNTECK?

Innteck, the Italian motorcycle-parts distributor founded in 2004 in Piedmont and part of the Athena group since 2023, develops off-road wear parts under its own brand with a carefully judged price-quality ratio.

When should you replace the gaskets on your KTM EXC 125?

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.
