ATHENA top-end gasket kit for KTM EXC 250 TPI, HUSQVARNA TE 250 and GAS GAS EC 250 from 2017 to 2023

ATHENA offers this top-end gasket kit for KTM EXC 250 TPI, HUSQVARNA TE 250 and GAS GAS EC 250 from 2017 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 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 top-end rebuild (manufacturer recommendation for the KTM EXC / XC-W, Husqvarna TE 250/300 2017-2023):

• Racing: every 40 h.
• Leisure: every 80 h.
• KTM SX, Husqvarna TC 125-300 2017-2022: racing: every 20 h.
