Product Overview

This full-aluminum engine cooling radiator is a perfect OEM replacement for 2023-2025 Kawasaki Ninja ZX-4R, ZX-4R SE and ZX-4RR ZX400 supersport motorcycles. Matches the original OEM part number 39060-0758 with 100% consistent mounting positions and overall dimensions. It effectively solves common faulty problems of stock radiators such as internal blockage, water leakage, poor heat dissipation and engine overheating during high-load riding. Adopting integrated all-aluminum welding process without glue filling, this radiator features stronger pressure resistance and durability, providing stable and efficient cooling protection for the 399cc inline four-cylinder high-power engine.

Core Features

• Full Aluminum Premium Construction: Made of high-density aluminum material with integral welding molding, abandoning traditional glue bonding process, effectively avoiding aging cracking and liquid leakage.
• High-Efficiency Heat Dissipation: Optimized core fin structure increases heat exchange area, rapidly takes away engine heat, maintains stable working temperature during street riding and track high-speed operation.
• Exact OEM Fitment: Strictly manufactured according to ZX400 ZX-4R factory standards, consistent with original mounting holes and interface positions, realizing plug-and-play bolt-on installation without any cutting or modification.
• Durable & Reliable: Excellent high temperature resistance, corrosion resistance and pressure resistance, adapting to high-power engine heat load, long service life and low failure rate.
• Overheating Prevention: Effectively improves the heat dissipation deficiency of old radiators, eliminates high-temperature boiling, power attenuation and other faults caused by poor cooling.

Fitment Compatibility

• Compatible with 2023-2025 Kawasaki Ninja ZX-4R / ZX-4R SE / ZX-4RR (ZX400) All Versions
• OEM Reference Number: 39060-0758 | Fits 399cc Inline 4-Cylinder Liquid-Cooled Engine
