MOOSE RACING complete engine gasket kit for KTM SX 250, GAS GAS EC 250 and HUSQVARNA TC 250 from 2023 to 2026

MOOSE RACING offers this complete engine gasket kit for KTM SX 250, GAS GAS EC 250 and HUSQVARNA TC 250 from 2023 to 2026. 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 MOOSE RACING?

Moose Racing has its gaskets made in the USA and supplies OEM-quality oil seals: everything needed for a leak-free rebuild, in a single kit.

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.
