Product Overview

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

The front wheel sensor assembly is the ABS speed sensing unit fitted to the front wheel hub, comprising a toothed reluctor ring and a sensing element that generates a pulse signal proportional to front wheel rotational speed. This signal is transmitted to the ABS control unit, which monitors it continuously to detect impending front wheel lock-up and modulate front brake pressure to maintain steering control under hard braking. A faulty, contaminated, or damaged sensor produces an incorrect or absent speed signal, triggering ABS warning indicators, disabling the ABS system, and compromising front braking safety. This original replacement is manufactured to original factory specifications, restoring accurate front wheel speed sensing and reliable ABS function on your Yamaha NMAX 125.

Complete Part Guide

On newer NMAX models, ABS works in split seconds, so the signal has to be spot on. The original Yamaha NMAX125 Front Wheel Sensor Assembly (B6H-H5970-00) for 2021-2024 models tracks wheel speed in real time, allowing the system to react instantly and keep the front wheel turning under braking. It's what keeps stops controlled, not sudden. Manufactured to original Yamaha specification for precise fitment and signal accuracy. Available from Part Hive, orders placed before 1 PM qualify for same-day UK dispatch from our London hub.

We see this issue regularly in the workshop. The rider states that the bike feels mostly fine under normal riding, but the problem only shows up when they actually need the ABS to work properly. On the Yamaha NMAX-125, even a slight fault in the front wheel sensor can throw off timing and make the system react late, jumpy, or inconsistent. Riders often don't notice anything wrong at first, then suddenly feel hesitation or odd pulsing under hard braking. Once we swap it out and fit the original Yamaha front wheel sensor assembly, the difference is clear. No delay, no strange behaviour, just clean, predictable braking that matches how the ABS was designed to work.
