PISTON KIT 96-99 KTM250 67.50, WOSSNER 8016DA FORGED
This Wossner forged piston kit is specifically designed for KTM 250 models from 1996 to 1999. With a 67.50mm standard bore, it delivers the structural reliability required in high-performance two-stroke engines. Manufactured in Germany, the piston features an elliptical profile that accommodates thermal expansion, ensuring uniform load distribution and reducing stress concentrations. This design enhances piston longevity and supports efficient heat transfer from the combustion chamber to the cylinder wall. Features forged piston construction for high durability and mechanical strength. The elliptical design distributes bearing surface load evenly under thermal expansion, preventing localised stress points and minimising the risk of piston collapse. Engineered for optimal heat transfer from the combustion chamber. Precision-manufactured in Germany. Specifications include a bore size of 67.50mm (Standard) with an actual diameter of 67.44mm. Compression height is 26.70mm, stroke is 69.50mm, and displacement is 249 cm³. Piston clearance is 0.06mm. Compression ratio is 2-stroke (Wossner and OEM). Wossner Piston Kit Part No: 8016DA. Includes Lock: CW18, Pin: WP033, Ring Set: RSB6750 x2, Rod: P2024. Weight is 440g.

FULL DESCRIPTION
Wossner Forged Piston Kit for KTM 250cc Two-Stroke Engines
This Wossner forged piston kit is engineered for high-performance applications, offering exceptional durability and reliability for your KTM 250cc two-stroke motorcycle. Manufactured in Germany to exacting standards, this piston is designed to withstand the rigors of demanding riding conditions.
Key Features:
- Forged Construction: Utilizes a forged aluminum alloy for superior strength, resilience, and resistance to fatigue compared to cast pistons.
- Elliptical Design: The piston features an elliptical profile that intelligently accommodates thermal expansion. This precise shaping ensures even load distribution across the piston's surface, reducing stress concentrations and preventing premature wear.
- Enhanced Longevity: By managing thermal expansion and distributing loads evenly, this design significantly extends the piston's service life and minimizes the risk of piston failure.
- Optimized Heat Transfer: Engineered to efficiently transfer heat away from the combustion chamber to the cylinder wall, contributing to stable engine temperatures and consistent performance.
- Precision Manufacturing: Made in Germany, guaranteeing high quality and adherence to strict manufacturing tolerances.
