PISTON KIT 16-22 SXF250 78 HC WOSSNER 8924DC KTM, HIGH COMPRESSION 79030207000, WOSSNER 8924DC KTM
Wossner 78mm piston kit with high compression. Bore size 77.96mm. Wossner forged pistons are superior in strength and design, engineered to provide the best possible path for combustion chamber heat transfer to cylinder walls. Elliptically designed to provide a more uniform bearing surface under piston heat expansion, eliminating localized pressure and distributing thrust loads more evenly, thereby preventing piston collapse. Made in Germany. Part number 56-W265.A.WO.HC. Piston size: 77.96mm. Lock P/N CW16. Pin P/N WP070. Ring Set P/N RIK78.00. Display (cm3) 249. Hub stroke (mm) 52.30. Clearance (mm) 0.05. Wossner compression ratio: 14.50:1. OEM compression ratio: 13.90:1. Dome volume (cm3) -0.94. Compression height (mm) 19.50. Theoretical weight (G) 135.00. Cross reference numbers: 79030207000, 40144M07800.

FULL DESCRIPTION
Wossner High Compression Piston Kit
This Wossner Piston Kit is designed for high-performance applications, featuring a high compression ratio for increased power output. Each piston is forged for superior strength and durability, and engineered for optimal heat transfer from the combustion chamber to the cylinder walls.
The elliptical design ensures a uniform bearing surface even under extreme heat expansion, eliminating localized pressure and distributing thrust loads evenly to prevent piston collapse. Precision manufacturing in Germany guarantees top-tier quality.
Key Features:
- Forged Piston: Superior strength and design for demanding use.
- Optimized Heat Transfer: Engineered for efficient combustion chamber heat management.
- Elliptical Design: Ensures uniform bearing surface and even thrust load distribution.
- High Compression Ratio: Achieves 14.50:1 compression, compared to the OEM 13.90:1.
- Precision Machining: Made in Germany for exceptional quality.
- Piston Diameter: 77.96mm (0.00mm Oversize).
- Compression Height: 19.50mm.
- Dome Volume: -0.94 cm3.
- Theoretical Weight: 135.00g.
- Includes: Lock Piston Pin (CW16), Pin Piston Pin (WP070), and Ring Set (RIK78.00).
Cross Reference Numbers: 79030207000, 40144M07800
