CENTAURO Valve Stem Seals - Set of 4 (manufacturer ref: P650903/4): parts intended for the refurbishment of cylinder heads for Quad, Cross, and Roadster. These seals, designed for intake, ensure sealing around the valve stem and limit oil intrusion into the combustion chamber, an essential role for a clean engine setting and smooth operation.
Manufactured to meet the requirements of regular maintenance, these Centauro seals are suitable for preparations and repairs on 2- and 4-stroke engines used off-road as well as on the road. They are suitable for interventions on the cylinder head during the replacement of guides or piston rings and integrate easily into a service kit.
Examples of models where these seals may be relevant: HONDA CRF 110 F (JE02), APRILIA SXV 450 (2017), HONDA CRF 50 F (AE04). For a clean and durable replacement, always check the valve stem diameter and manufacturer specifications before installation.
