A failing horn often loses volume or stops working altogether due to internal wear or weak electrical output. This original Yamaha NMAX 125 horn (2DP-H3371-00) fixes that by restoring a strong, clear sound signal. It ensures proper electrical flow through the unit. That allows the horn to produce full, consistent output. It's a simple fix that supports safer riding.

Vetted by our Lead Engineer. Leveraging 30 years of mechanical pedigree, every part is inspected for material density and exact tolerances to ensure a 'Right-First-Time' fit.

Product Overview

This high-quality Original Horn is designed to meet or exceed factory performance standards and is suitable for Yamaha NMAX 125 (2015-2020) models.

The horn is a safety-critical component that generates the motorcycle's audible warning signal, enabling the rider to alert pedestrians, other drivers, and road users to their presence in potentially hazardous situations. Over time, the horn's internal diaphragm can fatigue, the contact points can corrode, or the unit can develop an intermittent electrical fault, resulting in a weak, distorted, or completely absent sound that compromises rider safety and road-use compliance. This original replacement restores the original horn function, ensuring seamless, secure, and reliable operation of your NMAX 125.

Complete Part Guide

If your horn sounds weak, delayed, or barely noticeable in traffic, it's often because it's no longer producing enough output to properly alert other road users. Replacing it with the original Yamaha NMAX125 Horn (Part Number: 2DP-H3371-00) for 2015-2020 restores a strong, clear warning signal that helps you stay visible and safe on the road. A proper horn makes a real difference in busy urban riding where quick reactions matter. Manufactured to original Yamaha specification, it ensures precise fitment and reliable operation. Available from Part Hive's London hub, with same-day UK dispatch on all orders before 1 PM.

The horn isn't used constantly, but when it's needed, it has to work. On the NMAX-125, we see weakened horns caused by wear or electrical faults. That leads to inconsistent or low output. Riders often don't act until it becomes obvious. We test the wiring, check current flow, and confirm sound performance. Once it's not reliable, we install the original Yamaha horn. That brings back a clear, strong signal and ensures the rider has dependable warning capability in traffic.
