Description

A worn or damaged piston directly kills engine efficiency, compression, and reliability—especially in high-revving 2-stroke applications where tolerances are razor-thin. The Wossner 8942DA restores lost performance with German-engineered precision, using advanced forging techniques and FEA optimization to deliver the durability and power your YZ250F demands. This complete kit gives you everything needed for a straightforward rebuild without compromise.
