The kit containing every gasket needed to strip and rebuild the top end (cylinder and head) without leaks.
ATHENA offers this top-end gasket kit for KTM SX 250, SX 300, HUSQVARNA TC 250, TX 300 and GAS GAS EC 250, EC 300 from 2023 to 2027. 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.
The benefits:
Athena, original-equipment supplier to KTM and Ducati from Italy, laser-cuts its gaskets from materials designed for heat, oil and coolant.
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, Husqvarna TE, GASGAS EC two-strokes since 2024):
Cross-Mania tip: Clean the mating faces carefully without scratching them and tighten to the manufacturer's torque.
