Namura Technologies FX-20045-C Kawasaki Piston Kit +0.02mm (C) Oversize

The Namura Technologies FX-20045-C is a direct-replacement piston kit designed for Kawasaki engines, offered in a +0.02mm (C oversize) size — ideal for extending the life of expensive coated cylinders without requiring a full cylinder replacement. Built using a hypereutectic casting process, this piston delivers higher silicon content for reduced thermal expansion, improved wear resistance, and the ability to withstand elevated cylinder temperatures.

Key Features:

• MOS2 (Molybdenum/Teflon) Coated Skirts: Applied via a rolled-on process that bonds 10x stronger than spray-on coatings — reduces friction, improves heat transfer, and helps prevent cold seizures
• Machined Smooth Head: Reflects combustion heat and minimizes carbon buildup, with tests showing potential gains of up to 6% in horsepower and fuel economy
• Hard Anodized Dome: Increases heat resistance and durability; anodized pistons are up to 75% stronger than non-anodized alternatives
• Hypereutectic Alloy Construction: Higher silicon content reduces expansion rates and improves thermal tolerance for long-lasting performance
• C Oversize (+0.02mm): Specifically engineered to work with coated OEM cylinders, helping to maximize cylinder service life

Kit Includes:

• Individually wrapped piston
• OEM-quality piston rings (packaged separately)
• Wrist pin
• Circlips

Namura piston kits are available in a range of oversize increments — from 0.25mm up to 2mm in 0.25mm steps, as well as B (+0.01mm) and C (+0.02mm) oversizes — making it easy to find the right fit for your engine's needs. Select big bore kits are also available for certain applications.
