Wossner Piston Kit, 2.123 in Bore for Sherco (8303DA)

Upgrade your Sherco engine with the Wossner 8303DA Piston Kit, engineered for dependable performance, reduced friction, and long-term durability. This piston kit is forged from aerospace-grade aluminum alloy to provide a strong, lightweight foundation for high-performance applications while maintaining critical structural strength in the crown and skirt areas. Wossner’s precision-focused design supports consistent engine operation and responsive power delivery.
The piston features a permanent skirt coating designed to reduce friction and minimize piston rock. This helps promote quieter operation, smoother performance, and reduced wear during demanding riding conditions. Optimized machining removes unnecessary material while preserving strength in key areas, including the crown and skirt wall cross section, delivering a balanced combination of lightness and durability.
The Wossner 8303DA kit includes the piston, piston rings, wrist pin, and retaining clips for a convenient installation package. Designed for Sherco applications with a 2.123-inch piston diameter, this kit is suited for engine rebuilds, performance maintenance, and replacement of worn or damaged internal components. Verify vehicle and engine compatibility before installation to ensure proper fitment and performance.
