Product Overview

This high-quality Original Starter Relay Assy is designed to meet or exceed factory performance standards and is suitable for Yamaha NMAX 125 (2015-2024) models.

The starter relay assembly is the electromagnetic switch that bridges the gap between the battery and the starter motor, allowing the full cranking current to flow to the motor when the start button is pressed while protecting the handlebar switch controls. A faulty relay can result in no cranking response, a rapid clicking noise from the solenoid as the contacts fail to engage, or intermittent starting problems that become progressively more frequent as the internal contacts deteriorate. This original replacement restores the original starter circuit switching function, ensuring seamless, secure, and reliable operation of your NMAX 125.

Complete Part Guide

When you press the starter, this is the part that makes everything happen. The original Yamaha NMAX125 Starter Relay Assembly (5TP-H1940-01) for 2015–2024 models delivers power directly from the battery to the starter motor, ensuring the engine turns over without hesitation.

A very common issue we see is the NMAX-125 not starting consistently, sometimes it clicks, sometimes nothing happens. In the workshop, this is often traced back to the relay contacts wearing or burning out from repeated load. We see this quite regularly on daily-use scooters. Riders usually suspect the battery first and try replacing or charging it, but the issue remains. We replace it with the original Yamaha starter relay assembly and it restores proper current transfer, locks in securely, and delivers consistent starting performance without hesitation.
