CENTAURO Valve Stem Seals - Set of 4 (ref. P650946/4)
Set of 4 valve stem seals by CENTAURO, designed for the refurbishment of cylinder heads and the maintenance of motocross engines. These seals ensure a tight fit around the valve stem, on both the intake and exhaust sides, and are engineered to withstand the thermal and mechanical stresses encountered in off-road use.
Ideal for preparations and maintenance operations after several hours on the track, this set allows for the replacement of worn parts that compromise the sealing of the valve guides. Installation and verification are recommended when replacing guides or during a complete cylinder head overhaul.
Examples of models for which this reference is commonly used: HUSQVARNA FC 350 (2025 - 350 cm3), KTM 250 SX-F (2025 - 250 cm3), GAS GAS MC 250 F (2025 - 250 cm3). Please check compatibility with your motorcycle before ordering.
