PISTON KIT XR XLR 500 91.00, FORGED WOSSNER 8642D200

Wossner Forged Piston Kit - 91.00mm Bore

Upgrade your engine's performance and durability with this Wossner forged piston kit. Engineered for superior strength, this piston is designed to withstand higher combustion pressures and temperatures compared to cast pistons. Its advanced elliptical design ensures even distribution of thrust loads, which helps prevent localized pressure and reduces the risk of piston collapse, even under extreme operating conditions. Manufactured to exacting standards in Germany, this kit provides optimal combustion efficiency and reliability.

Key Features:

• Forged Construction: Provides significantly increased strength and longevity.
• Optimized Heat Transfer: Enhances thermal efficiency for improved performance.
• Elliptical Piston Design: Promotes a uniform bearing surface as the piston expands with heat, reducing wear.
• Even Thrust Load Distribution: Prevents localized stress and reduces the likelihood of piston failure.
• German Manufacturing: Ensures high quality and precision engineering.
