Yamaha N-Max 125 15-24 / X-Max 125 21-25 RB Max valve seal

Yamaha N-Max 125 2015-2024 / X-Max 125 2021-2025 RB Max valve stem seal

The RB Max 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 train 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 promote the passage of oil into combustion and increase lubricant consumption, so its replacement is part of the usual engine maintenance tasks.

This spare part is designed to replace the original component, making it possible to restore the correct sealing at the valve guide and maintain the proper operation of the valve train system.
