Product Overview

This high-quality Original Radiator Assembly is designed to meet or exceed factory performance standards and is suitable for Yamaha NMAX 125 (2021-2024) models.

The radiator assembly is the central component of the liquid cooling system on the NMAX 125, circulating engine coolant through its core to dissipate heat generated during combustion and maintain optimal engine operating temperature. A damaged, cracked, or corroded radiator can cause coolant loss, persistent overheating, and serious engine damage if left unaddressed. This original replacement is manufactured to original factory specifications, ensuring correct coolant flow, precise fitment, and the heat transfer performance required to keep the NMAX 125 engine running at a safe and efficient operating temperature.

Complete Part Guide

When you're stuck in traffic and the temperature starts creeping up, it's usually the cooling system struggling to keep up. This original Yamaha NMAX125 Radiator Assembly (Part Number: B6H-E240A-01) for 2021-2024 dissipates heat from the coolant to maintain stable engine temperature. Manufactured to original Yamaha specification, it ensures precise fitment and efficient heat transfer under real riding conditions. In stop-start London riding, this is one of the hardest-working components on the bike. Available from Part Hive's London hub, with same-day UK dispatch on all orders before 1 PM.

London traffic doesn't give the cooling system much room to recover. On the NMAX-125, we see overheating linked to radiators struggling to dissipate heat properly. Debris buildup or internal restriction is common. Riders often try coolant changes or ignore early signs. We check airflow through the fins, test coolant circulation, and inspect the radiator condition. Once it's not performing as it should, we fit the original Yamaha radiator assembly, restoring efficient heat control and preventing further temperature issues.
