Wossner Forged Piston kitRef : WO00508A / 1093519002

The WÖSSNER forged piston ref. 8083DB is a part designed for motocross riders looking for a reliable workshop reference for their top-end. Machined in Germany by Wössner, this forged aluminum piston features a robust design suited to the demands of off-road engines.

• Type: forged piston, anti-friction treated skirt
• Material: aluminum
• Piston diameter: Ø 77.950 mm (indicated diameter 77.95 mm)
• Recommended bore: 78.01 mm
• Oversize: Letter B (oversize)

Designed to be installed in prepared cylinders, this piston particularly fits the KTM 380 motocross machines (models 1999–2002 listed). The skirt finish minimizes friction during startup and at high RPMs, while the forged construction provides superior mechanical strength against the stresses typical of off-road use.

Whether for an engine overhaul or restoration, the WÖSSNER 8083DB piston offers a precise replacement solution that complies with manufacturer specifications. Check the exact compatibility with your engine before installation and follow the assembly and break-in protocol recommended by the manufacturer.
