PISTON KIT 97-01 CR250 66.40 A, WOSSNER 8001DA HONDA MX

Wossner Forged Piston Kit for Honda CR250R (1997-2001)

Enhance the performance and durability of your Honda CR250R with this precision-engineered Wossner forged piston kit. Designed for 1997-2001 models, this kit features a standard bore size of 67.40mm and is manufactured in Germany using advanced forging techniques.

The piston's unique elliptical design is crucial for managing thermal expansion. By distributing stress evenly across the piston, it prevents localized pressure points and the risk of piston collapse, especially under demanding operating conditions. This intelligent design also optimizes heat transfer from the combustion chamber to the cylinder wall, ensuring consistent performance and extended component life.

Key Features:

• Forged piston construction for superior strength and wear resistance.
• Elliptical shape promotes even thermal expansion.
• Reduces the likelihood of piston collapse by uniformly distributing thrust loads.
• Optimized for efficient heat dissipation from the combustion area.
• Precision engineered and manufactured in Germany.
