The Wossner 8699DB forged piston kit is a high-compression piston with a 95.51mm bore, specifically designed for Suzuki LTR450 models from 2002 to 2011. This German-engineered piston improves heat management and durability through its forged construction and elliptical design, which distributes pressure evenly and prevents piston collapse during high-temperature operation.

Features

• High-compression forged piston for increased strength and performance


• Designed for optimal heat transfer from combustion chamber to cylinder walls


• Elliptical design ensures uniform load distribution under heat expansion


• Reduces risk of localized pressure and piston collapse


• Manufactured in Germany
