Wiseco YZ250 2002-2022 Piston Kit with Gaskets PK1704

When you're rebuilding a YZ250 top end, you need a piston kit that delivers consistent performance lap after lap without compromise. The Wiseco PK1704 is engineered specifically for the 2002-2022 YZ250 platform, combining forged construction with advanced coatings to handle the demands of both competition and trail riding. This complete kit eliminates the guesswork—you get everything necessary for a proper rebuild in one package.

The high-silicon aluminum alloy forging provides the strength needed to resist detonation and micro-welding, while the E-coating on critical surfaces extends component life in high-heat environments. The elimination of boost ports creates a more linear powerband with stronger top-end pull, giving you predictable throttle response when it matters. Reduced exterior machining improves ring sealing and compression efficiency, translating to better performance and reliability.
