PISTON KIT 03-09 RM250 67.40, NAMURA NX-30027-4 SUZUKI
Namura piston kit 67.40mm bore. High-performance Namura pistons are engineered in the USA and manufactured in Taiwan. High-silicon content hypereutectic cast aluminum material for less heat expansion, tighter clearances, increased hardness, longer life, and reduced scuffing. Machined, smooth piston crowns reduce carbon buildup, increasing horsepower and fuel economy. Hard anodized crowns are 75% stronger than non-anodized, providing minimal expansion and reducing the chance of cold seizures when combined with Teflon/Molybdenum coated skirts. MOS2 (Teflon/Molybdenum) coated skirts reduce friction and heat for added power and longevity. Namura rings match the OEM design. Fractional oversize pistons are available for some applications to extend cylinder life. Part No. 56-W823_100.NT. Cross reference number NX-30027-4.

This high-performance Namura piston kit is engineered in the USA and manufactured in Taiwan. It features a 67.40mm bore size, designed to meet or exceed OEM specifications for select Suzuki RM250 models.
Key Features:
- High-Silicon Content Hypereutectic Cast Aluminum: This advanced material offers reduced heat expansion, tighter clearances, increased hardness, longer life, and reduced scuffing.
- Machined, Smooth Piston Crowns: Designed to minimize carbon buildup, leading to increased horsepower and improved fuel economy.
- Hard Anodized Crowns: Provides 75% greater strength than non-anodized crowns, minimizing expansion and reducing the risk of cold seizures.
- Teflon/Molybdenum Coated Skirts (MOS2): These specially coated skirts reduce friction and heat, contributing to enhanced power and engine longevity.
- OEM-Style Rings: The included piston rings are designed to match OEM specifications for reliable performance.
- Oversize Piston Options: Available in fractional oversize increments (-B and -C) for certain applications, allowing you to extend the life of your cylinder by restoring original clearances if slightly worn, avoiding costly sleeving.
This piston kit is a direct replacement for part number NX-30027-4.
