The piston's skirt is also optimized for a perfect fit in the cylinder, reducing friction and ensuring a smooth running engine. The piston's top ring is a 1.2mm thick, 100% chrome molybdenum alloy, ensuring excellent sealing performance and longevity.

The Wiseco 677M06900 Piston is also equipped with a 100% chrome molybdenum alloy second ring, which is .7mm thick to provide additional sealing performance. The piston's third ring is a 1.3mm thick, 100% chrome molybdenum alloy, providing excellent oil control and longevity.

Installing the Wiseco 677M06900 Piston is a straightforward process, thanks to the included piston pin, piston pin retainer, and wrist pin clip. The piston also includes a ring pack, which includes the top ring, second ring, and third ring, as well as their respective ring groove seals.

In conclusion, the Wiseco 677M06900 Piston is a high-performance upgrade for your Yamaha WR250 and YZ250 models. Its forged aluminum alloy construction, optimized dome shape, and full-floating wrist pin ensure superior strength, durability, and power.
