Product Overview

This high-quality Aftermarket Air Filter is designed to meet or exceed factory performance standards and is suitable for Yamaha NMAX 125 (2021-2025) models.

The air filter protects the engine by capturing dust, road grit, and airborne particles from the incoming airstream before they can reach the throttle body and combustion chamber. A clogged or deteriorated filter element restricts airflow, upsets the air-fuel balance, and leads to sluggish throttle response, rough running, and elevated fuel consumption. This Aftermarket replacement is designed to match the original part, restoring clean, unrestricted airflow and protecting your Yamaha engine at every service interval.

Complete Part Guide

Stop-start city riding pulls in more dust and debris than you think. The aftermarket Yamaha NMAX 125 Air Filter (B6H-E4451-00) for 2021-2025 restores clean airflow by trapping contaminants while maintaining consistent intake performance. Precision-moulded and engineered for fit and function, it installs directly with no modification and matches factory mounting points. Built for durability under real commuting conditions. Available with same-day UK dispatch for orders placed before 1 PM from our London hub.

We've had Yamaha NMAX-125s come in where the rider says the throttle just feels a bit flat or delayed. Most of them have already tried basic things, checking the fuel, even adding cleaner, thinking it's something else. But when we check it, the airflow's restricted. The filter's usually clogged from everyday riding, especially in stop-start traffic. We've also seen some that don't sit right and don't seal properly. We replace it with a proper aftermarket Yamaha air filter, and it sorts it so the engine breathes properly again, and throttle response comes back straight away.
