The Wossner 8168DA piston kit is a standard-size forged piston with a 66.40mm bore and 66.34mm piston diameter. This piston is designed for maximum strength and optimal heat transfer in two-stroke engines. Its elliptical design provides a uniform bearing surface under thermal expansion, reducing localized stress and preventing piston collapse. Manufactured in Germany, this piston ensures long-lasting, reliable performance. Features include forged construction for superior strength and durability, design for efficient heat transfer, an elliptical piston shape for uniform expansion and balanced load distribution, and precision manufacturing in Germany. Specifications include a bore of 66.40 mm, piston diameter of 66.34 mm, display displacement of 249 cm³, stroke of 72.00 mm, piston clearance of 0.06 mm, compression height of 37.00 mm, 2-stroke compression ratio, lock part number CW18, pin part number WP033, and ring set part number RSB6640 x 2. Cross-reference OEM part numbers include 13001-0058, 09104860, and 843M06640.
