Product Overview

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

The spark plug cap assembly transmits the high-voltage electrical pulse from the ignition coil to the spark plug, providing the spark required to ignite the fuel mixture in the combustion chamber. A deteriorating or cracked cap can allow electrical energy to leak, resulting in weak or missed sparks, rough running, misfires, and inconsistent engine performance. This original replacement ensures a secure, properly insulated connection between the ignition lead and spark plug, restoring reliable ignition to your NMAX 125.

Complete Part Guide

When the bike struggles to start or runs inconsistently, it's often due to a weak or unstable electrical connection in the ignition system. Replacing it with the original Yamaha NMAX125 Spark Plug Cap Assembly (Part Number: BK6-H2370-00) for 2021-2024 restores proper voltage transfer so the engine can fire reliably every time. Built to Yamaha's original standards, it ensures secure fitment and dependable performance. Once sorted, the engine runs smoother and more consistently. Available from Part Hive's London hub, with same-day UK dispatch on all orders before 1 PM

A strong spark depends on a solid connection. On the NMAX-125, we see worn plug caps causing inconsistent ignition because they don't grip or conduct properly anymore. That leads to uneven running and reduced efficiency. Riders often try replacing the spark plug, but the issue stays. We remove the cap, inspect internal wear, and test how well it conducts current. Once it's not performing as it should, we install the correct original Yamaha spark plug cap assembly, restoring proper contact and bringing the engine back to smooth, stable operation.
