Refresh your 2-stroke top end with the WOSSNER 8169DA piston kit, forged from aerospace-grade aluminum for strength with low weight. A permanent skirt coating helps reduce friction and piston rock for smoother, quieter performance.
Bring back crisp compression and reliable power with the WOSSNER Piston Kit for 2-stroke engines (8169DA). Forged from aerospace-grade aluminum alloy and precisely machined for reduced weight while maintaining strength in critical areas (crown and skirt wall cross-section), this kit is a smart choice for a top-end refresh. The high-quality permanent skirt coating reduces friction and helps minimize piston rock—supporting quieter running and improved performance under load.
If your 250cc TBi 2-stroke is showing signs of wear (loss of compression, harder starting, reduced throttle response), replacing the piston assembly is one of the most effective ways to restore performance and reliability. This kit includes the core components needed for a proper rebuild, making the job simpler and ensuring parts are matched.
