Wossner Piston Kit, 53.95 mm for Yamaha (8331DA)

Upgrade your Yamaha engine with the Wossner 8331DA Piston Kit, engineered for dependable performance, reduced friction, and long-lasting durability. This piston is forged from aerospace-grade aluminum alloy to provide an excellent balance of strength and light weight. Optimized machining removes unnecessary material while maintaining critical support in the crown and skirt wall cross-section, helping the piston perform reliably under demanding operating conditions.
The permanent skirt coating is designed to reduce friction and minimize piston rock, contributing to quieter operation and smoother engine performance. This coating also supports consistent piston movement within the cylinder, helping improve efficiency and durability during repeated use. The 53.95 mm piston size is manufactured for compatible Yamaha applications and should be matched to the engine’s specifications before installation.
The Wossner 8331DA kit includes the essential components needed for piston replacement: one piston, piston rings, wrist pin, and retaining clips. Each component is selected to work together as part of a complete replacement solution, simplifying installation and helping restore proper engine operation. Verify application compatibility, bore requirements, and installation clearances before use to ensure correct fitment and performance.
