Product Overview

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

The Inlet & Exhaust Valve Set provides the complete set of intake and exhaust poppet valves in a single service kit, allowing full valve renewal in one supply. The intake valves open to admit the air-fuel charge, while the exhaust valves open to release spent gases, with all valves sealing the combustion chamber during the remaining strokes. When any valve face or seat recedes, burns, or develops pitting, compression drops, power decreases, idle quality deteriorates, and fuel consumption rises. This original replacement is manufactured to original factory specifications, restoring reliable engine performance to your Yamaha NMAX 125 scooter.

Complete Part Guide

Engine performance also depends on how well the air and fuel are controlled. This original Yamaha NMAX125 inlet and exhaust valve set (2DP-E2111-00, 2DP-E2121-00) manages airflow through the engine, helping maintain smooth performance and efficient operation. Built to Yamaha's standards, it delivers precise sealing, accurate timing, and dependable durability. Available now from Part Hive's London hub, order before 1 PM for same-day UK dispatch.

Because these components are in constant motion, wear builds up over time. A common issue is reduced efficiency caused by valves no longer sealing correctly on the NMAX-125, often due to heat cycles and carbon deposits. It's something we regularly see during engine inspections. The drop in performance can be gradual, so it's not always obvious at first. We replace them with the correct original Yamaha inlet and exhaust valve set and it restores proper sealing, smooth operation, and a precise factory fit.
