Yamaha Ya-6 125cc, 0.50mm Over-the-Stroke (OS) Piston Kit (137-11636-61)

The Yamaha 137-11636-61-96 piston kit is specifically designed for Yamaha Ya-6 engines with a 125cc displacement and a 0.50mm over-the-stroke (OS) piston size. This piston kit is an excellent replacement option for those in need of a piston upgrade or engine rebuild.

The piston itself is made of high-quality materials to ensure durability and reliable performance. The piston crown is designed for optimal combustion efficiency, providing better power output and fuel economy. The skirt of the piston is machined to tight tolerances to ensure a proper fit within the engine's cylinder bore.

The piston ring set included in this kit features compression rings and oil control rings. The compression rings are designed to provide a good seal between the piston and cylinder wall, ensuring proper compression and power output. The oil control rings help prevent oil from entering the crankcase, reducing blowby and improving engine efficiency.

The piston pin that comes with this kit is precision-machined to ensure a proper fit within the piston and connecting rod. The piston pin is also designed for a long service life, with a hardened surface to resist wear and tear.

The piston kit also includes a piston pin retainer, which securely holds the piston pin in place. This retainer is made of strong and durable materials to ensure a long service life and reliable performance.

In summary, the Yamaha 137-11636-61-96 piston kit is a high-quality replacement option for those in need of a piston upgrade or engine rebuild for their Yamaha Ya-6 125cc engine. The piston, piston rings, piston pin, and piston pin retainer are all made of high-quality materials and designed for optimal performance and long service life.
