FULL DESCRIPTION

Wossner Forged Piston Kit Big Bore 83.00mm

Upgrade your engine's performance and durability with the Wossner forged piston kit. This kit features a big bore design for increased displacement and power. Engineered for optimal heat transfer, the piston efficiently dissipates heat from the combustion chamber to the cylinder walls, contributing to improved overall engine performance and longevity. The unique elliptical design ensures a uniform bearing surface, even under extreme heat expansion, effectively reducing localized pressure and distributing thrust loads evenly to prevent piston collapse.

Key Features:

  • Forged Construction: Offers superior strength and resilience compared to cast pistons, providing enhanced durability for demanding applications.
  • Optimized Heat Transfer: Designed to efficiently move heat away from the combustion chamber, promoting cooler operation and improved performance.
  • Elliptical Design: Prevents localized pressure points and ensures even load distribution, eliminating the risk of piston collapse under high temperatures.
  • Pro Series Two-Ring Configuration: This design enhances sealing capabilities for improved compression and longevity of the piston rings.

Specifications:

  • Bore Size: 82.96 mm
  • Piston Diameter: 83.00 mm
  • Displacement: 249 cm³
  • Stroke: 53.60 mm
  • Piston to Cylinder Clearance: 0.04 mm
  • Wossner Compression Ratio: 12.80:1
  • OEM Compression Ratio: 12.50:1
  • Dome Volume: -4.80 cm³
  • Compression Height: 20.50 mm
