FULL DESCRIPTION

Wossner 90.00mm Piston Kit for Honda CR500 & CR480

Upgrade your motorcycle's engine with this high-performance Wossner piston kit. Engineered for durability and optimal power output, this kit is manufactured in Germany to exacting standards.

The forged construction of this piston provides superior strength and resistance to wear, ensuring a longer lifespan for your engine. Its innovative elliptical design plays a crucial role in performance by evenly distributing thrust loads. This design accounts for thermal expansion, reducing localized pressure points and preventing potential piston collapse, especially under demanding riding conditions.

Furthermore, this piston is optimized for efficient heat dissipation. It effectively transfers heat away from the combustion chamber to the cylinder walls, helping to maintain optimal operating temperatures and prevent overheating, which is critical for consistent performance and engine longevity.

Key Features:

  • Forged construction for enhanced durability and strength.
  • Elliptical design for even distribution of thrust loads during thermal expansion.
  • Optimized for effective heat transfer from the combustion chamber to the cylinder walls.
  • Manufactured in Germany for superior quality assurance.

Specifications:

  • Bore Size: 90.00mm (actual 89.92mm)
  • Displacement: 500 cm³
  • Stroke: 79.00 mm
  • Clearance: 0.08 mm
  • Compression Height: 40.00 mm
  • Compression Ratio: 2-stroke (compatible with Wossner and OEM specifications)
