Yamaha X-Max 125 valve half-cones 06-13

Valve cotters original replacement part for Yamaha X-Max 125 06-13.

The Yamaha valve cotters are high-precision machined metal components responsible for securing the spring retainer to the engine valve stem. Their function is to keep the assembly under the correct spring tension to prevent the valve from dropping into the combustion chamber during the operating cycle.

With continued use, high engine speeds, and repeated disassembly operations on the cylinder head, these tapered keys may suffer wear due to friction or deformation of their locking tabs. It is recommended to replace the valve cotters whenever valves are replaced or a complete cylinder head rebuild is carried out on 4-Stroke engines in order to prevent catastrophic valve timing failures.

As this is an original Yamaha replacement part, this component matches the exact tolerances specified by the manufacturer, ensuring correct seating on the valve stem without play.
