INNTECK Top End Gasket Kit for KTM EXC 125, SX 125 1991-1997

INNTECK offers this top-end gasket kit for KTM EXC 125, SX 125 1991-1997. The top end is the cylinder, piston and cylinder head. When they are taken apart, the gaskets sealing them are crushed and cannot be reused.

Why buy a complete kit?

The benefits:

• Every top-end gasket in one part number: nothing is forgotten at reassembly.
• Cheaper than buying the gaskets one by one.
• New gaskets guarantee compression and sealing against water, oil and gases.

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.

No manufacturer hour figure for this model. Cross-Mania guideline: compression check every 20 h in hard use and every 40 h for leisure.
