WÖSSNER Forged Piston – Manufacturer Ref. 8183D050

Made in Germany, this Wössner forged piston is designed for riders and tuners looking for a replacement engine part for quads and motocross machines. Constructed from forged aluminum, it maintains a compact structure suited to the thermomechanical stresses encountered in intensive use.

• Bore diameter: 49.50 mm
• Piston diameter: Ø 49.45 mm (oversize 050)
• Material: forged aluminum
• Number of rings: 1
• Anti-friction treatment on the skirt to limit wear
• Delivered complete: ring(s), circlips, and piston pin

The oversize 050 corresponds to a piston suitable for a +0.50 mm re-bore; check the bore and specifications of your cylinder before installation. The skirt treatment reduces hot friction and facilitates the break-in process. This part is ready to be installed during an engine overhaul or for off-road preparation.
