WÖSSNER Forged Piston - Manufacturer Ref. 8266DA

Designed for off-road displacements, this Wössner forged piston meets the expectations of demanding motorcyclists for engine parts. Machined from aluminium and treated at the skirt to reduce friction, it comes ready to install with its rings, circlips, and pin. This part is intended for cross use, compatible with the Yamaha YZ 490 (years 1982–1984) according to manufacturer specifications.

  • Forged aluminium piston
  • Bore diameter: 87.00 mm
  • Piston diameter: Ø 86.920 mm (oversize letter: A)
  • Number of rings: 2
  • Supplied with rings, circlips, and pin

The design and finish of the skirt limit friction during the initial uses and facilitate the running-in process. This piston is offered in oversize version A: check the bore of your cylinder before installation. For safe installation, follow the manufacturer's recommendations regarding side clearance, torque settings, and running-in procedure.
