Product Overview

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

The starter brush set consists of the carbon contact brushes within the electric starter motor of the Yamaha NMAX 125, maintaining continuous electrical contact with the motor's commutator to transfer current and generate the rotational force needed to crank the engine. As the carbon brushes wear down through normal use, electrical contact weakens, resulting in slow cranking, intermittent starting, or complete starter motor failure if left unaddressed. This original replacement is manufactured to original factory specifications, restoring full electrical contact and reliable starter motor performance on the NMAX 125.

Complete Part Guide

When the starter motor feels weak or inconsistent, it's usually because the internal brushes aren't transferring power properly. Fitting the original Yamaha NMAX125 Starter Brush Set (Part Number: 5TP-H1801-00) for 2015-2020 restores that connection so the motor can turn the engine over smoothly. Built to the original Yamaha specification, it ensures reliable conductivity and correct fitment. That consistent power transfer is what makes starting feel instant again. Available from Part Hive's London hub with same-day UK dispatch on all orders before 1 PM.

Riders often assume a weak start means a bad battery, but we check the starter brushes early on the NMAX-125. These brushes carry current through the motor, and when they wear, performance drops. We see inconsistent cranking and delayed starts. Riders usually try charging or replacing the battery first. We remove the starter motor, inspect brush wear and contact surfaces, and confirm the issue. Then we install the original Yamaha starter brush set, restoring efficient current transfer and bringing the starting system back to a consistent, dependable condition.
