PISTON KIT SX-F450 KTM HC 97, FORGED WOSSNER 8715DC
Wossner forged piston kit with a 97.02mm bore and 96.98mm diameter. This high-compression piston (13.50:1) enhances performance and durability. Manufactured in Germany, it ensures optimal heat transfer to cylinder walls. Its elliptical design provides a uniform bearing surface under heat expansion, reducing localized pressure and evenly distributing thrust loads to prevent piston collapse. Features include forged construction for superior strength, high-compression ratio for increased performance, optimized heat transfer for efficient combustion, elliptical design for uniform load distribution, and German manufacturing. Specifications: Bore 97.02mm, Diameter 96.98mm, Display (cm³) 449, Stroke (mm) 68.80, Clearance (mm) 0.04, Wossner Compression Ratio 13.50:1, OEM Compression Ratio 12.50:1, Dome Volume (cm³) +1.10, Compression Height (mm) 21.30. Cross-Reference OEM Part Numbers: Wossner Piston KTM SX-F450 (PN# 8715DC), Lock P/N: CW19, Pin P/N: WP071, Ring Set P/N: 970ADS, Connecting Rod Kit P/N: P4017.

FULL DESCRIPTION
Wossner Forged Piston Kit - High Compression for KTM SX-F450
Enhance the performance and durability of your KTM SX-F450 with this premium forged piston kit from Wossner. Engineered for high-compression applications, this piston delivers a noticeable boost in power while maintaining robust construction for longevity.
Key Features:
- Forged Construction: Provides superior strength and resilience compared to cast pistons, capable of withstanding higher stresses and temperatures.
- High Compression Ratio: Features a 13.50:1 compression ratio, significantly higher than the OEM 12.50:1, for increased power output and throttle response.
- Optimized Heat Transfer: Manufactured in Germany, this piston is designed for efficient heat transfer to the cylinder walls, promoting optimal combustion and preventing overheating.
- Elliptical Design: The innovative elliptical shape ensures a uniform bearing surface even under extreme heat expansion. This reduces localized pressure points and distributes thrust loads evenly, preventing piston distortion and collapse.
- German Engineering: Built to exacting standards in Germany, guaranteeing precision and quality.
