Features

WÖSSNER Forged Piston designed for motocross and demanding motors. Manufactured in Germany by a specialist in engine parts, this forged aluminum piston meets the quality standards expected by motocross riders: robustness, machining precision, and play control. Ideal for maintenance operations or refurbishment after an off-road season. Manufacturer reference: 8186D050.

  • Type: forged piston
  • Material: aluminum
  • Bore diameter: 48.50 mm / Piston diameter: Ø 48.45 mm (oversize letter 050)
  • Compression: standard
  • Anti-friction treatment of the skirt to limit hot friction
  • Delivered complete: ring(s), circlips, and pin

This Wössner piston is intended for motocross displacements requiring a precisely fitted part (oversize +0.50). The treated skirt helps preserve the contact surface and facilitates the break-in process, while micron machining ensures proper concentricity for mounting on the corresponding bore. Compatible notably with YAMAHA YZ 80 (1985–1987) — check the bore size before installation.

Installation and control: follow the manufacturer's recommendations for piston-wall clearance, torque specifications, and break-in. Product delivered ready for installation, ideal for restoring the mechanics after off-road use without improvisation.
