Yamaha N-Max 125 15-26 / X-Max 125 21-26 Athena valve stem seal

Athena valve stem seal for Yamaha N-Max 125 2015-2024 / X-Max 125 2021-2025.

The Athena valve stem seal is a component designed to control the flow of oil between the cylinder head and the valve guide in 4-stroke engines. Its function is to maintain the sealing of the valve timing system, preventing an excessive amount of lubricant from reaching the combustion chamber.

Wear of the valve stem seals can cause symptoms such as bluish smoke from the exhaust, especially during cold starts or during engine braking phases. Material degradation can allow oil to pass into combustion and increase lubricant consumption, so its replacement is part of routine engine maintenance tasks.

This replacement part is designed to replace the original component, restoring proper sealing at the valve guide and maintaining the correct operation of the valve timing system.
