PISTON KIT 97-01 CR250 66.40 A, NAMURA NX-10025-A HUSQVARNA

Namura Piston Assembly - 66.4mm Bore

This high-performance Namura piston assembly is engineered in the USA and manufactured in Taiwan. It is designed to replace the original piston for optimal performance and longevity.

Key Features:

• High-Silicon Content Hypereutectic Cast Aluminum: This material is chosen for reduced heat expansion, tighter clearances, increased hardness, longer life, and reduced scuffing.
• Machined Smooth Piston Crowns: Reduces carbon buildup, leading to increased horsepower and improved fuel economy.
• Hard Anodized Crowns: These crowns are 75% stronger than non-anodized versions, providing minimal expansion and reducing the chance of cold seizures.
• Teflon/Molybdenum Coated Skirts (MOS2): These coatings reduce friction and heat, ensuring optimal performance even under demanding conditions.
• OEM Style Rings: Namura rings match original equipment designs.
• Oversize Piston Options: Available in fractional oversize options (.0004 in. and.0008 in.) to extend cylinder life by renewing original clearance.
• Complete Kit: Piston assemblies include the ring(s), wrist pin, and circlips.
