WÖSSNER Forged Piston – Piston set designed for motocross, manufactured in Germany by Wössner, a recognized specialist in engine parts for 2 and 4-stroke engines. This forged aluminum piston is intended for demanding displacements, where machining precision and durability are essential.

• Manufacturer reference: 8017D050
• Material: forged aluminum
• Compression: standard
• Recommended bore diameter: 72.50 mm
• Piston diameter: Ø 72.430 mm (Ø 72.43 mm)
• Oversize letter: 050
• Treatment: skirt with anti-friction treatment
• Supplied with: ring(s), circlips, and pin

The finish and machining tolerances of this piston meet the demands of off-road use: high revs, rapid load changes, and abrasive conditions. The treated skirt reduces friction during startup and racing conditions, while the forged alloy provides mechanical homogeneity suitable for the thermal stresses of motocross.

Examples of compatible models: KTM 300 EXC SIX DAYS (2003), KTM 300 EXC (2003), KTM 300 EGS (1999). Always check the bore size and reference before installation to ensure compatibility and correct clearances.
