FULL DESCRIPTION
Wossner 81mm Piston Kit
This Wossner piston kit is designed for high-performance engines, featuring a forged construction for superior strength and advanced design. Engineered to optimize combustion chamber heat transfer to the cylinder walls, this piston promotes efficient engine operation.
The elliptical design ensures a uniform bearing surface, even under extreme heat expansion. This feature helps to prevent localized pressure and distributes thrust loads more evenly, thereby preventing piston collapse and ensuring a longer lifespan.
Key Features:
- Forged construction for enhanced strength and durability.
- Engineered for optimal heat transfer from the combustion chamber to cylinder walls.
- Elliptically designed to provide uniform bearing surface under heat expansion.
- Distributes thrust loads evenly, preventing piston collapse.
- Gas ported for improved ring seal and reduced blow-by.
- Double bridge forging for added structural integrity.
- Constructed from high-quality 2618-T6 alloy.
- Piston bore size: 81.00mm.
- C grade piston size: 80.97mm.
- Compression ratio: 14.40:1.
- Includes RIK81.00 rings and WP070-SP piston pin.
- Piston weight: 150.9g.
- Made in Germany.
