COMETIC top-end gasket kit for KTM SX 125, SX 150, HUSQVARNA TC 125, TE 150 and GAS GAS MC 125, TXT 125 RACING from 2016 to 2023

COMETIC offers this top-end gasket kit for KTM SX 125, SX 150, HUSQVARNA TC 125, TE 150 and GAS GAS MC 125, TXT 125 RACING from 2016 to 2023. 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 COMETIC?

Cometic has made its gaskets in the USA since 1989: Viton-coated multi-layer steel (MLS) head gasket, the technology used in racing engines.

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.
