PISTON KIT SACHS 125/6 55.50, WOSSNER 8286D150 PIN 15mm
This Wossner forged piston kit features a 55.50mm bore and is an oversized (+1.50mm) replacement. Manufactured in Germany, it offers enhanced strength and efficient heat transfer. The elliptical design ensures uniform expansion and pressure distribution under operating conditions, reducing stress and preventing piston failure in two-stroke applications. Forged construction provides superior strength and durability. Designed for optimal heat dissipation from combustion to cylinder walls. The elliptical profile provides a uniform bearing surface under thermal expansion. Even thrust load distribution reduces localised stress. Specifications include a bore of 55.50mm (+1.50mm Oversize) with an actual bore of 55.44mm, display volume of 122 cm³, stroke of 54.00mm, clearance of 0.06mm, compression ratio of 2-stroke for both Wossner and OEM, and a compression height of 38.00mm. Cross-reference OEM part numbers include 56-W9843.150, 8286DB, clip part number CW15, pin part number WP132, and ring set part number RSB5550 (x2). Pin size is 15mm.
