Features

WÖSSNER Forged Piston Ref. 8263D150

Forged aluminum piston, designed and manufactured in Germany by Wössner for 2-stroke and 4-stroke engines. This piston offers a durable solution for the renovation or restoration of a roadster engine: anti-friction treated skirt, meticulous finish of the surfaces, and controlled tolerances for a precise fit in the bore.

Type: forged piston
Material: aluminum
Piston diameter: Ø 86.420 mm (indicated Ø 86.42 mm)
Recommended bore diameter: 86.50 mm
Letter oversize: 150
Compression: standard
Delivered with ring(s), circlips, and pin
Treatment: anti-friction skirt

Ideal for replacement operations during engine renovation or to restart a twin/single-cylinder engine that needs a reliable part. Compatible with the engines listed in the technical data sheet — among common applications, the YAMAHA DT 400 (1976–1978) is specifically mentioned as a reference for use. Installation and wear check are mandatory: adhere to bore tolerances and manufacturer recommendations during replacement (piston/cylinder clearance, type of ring, and assembly).
