Product Overview

This high-quality Original Exhaust Valve x2 Set is designed to meet or exceed factory performance standards and is suitable for Yamaha NMAX 125 (2015-2020) models.

The Exhaust Valve x2 Set provides a pair of precision-ground exhaust poppet valves that open on the exhaust stroke to release spent combustion gases and seal the exhaust ports during the intake, compression, and combustion strokes. Operating under extreme heat and pressure, exhaust valves are highly susceptible to burning, recession, and seat wear. When worn or burned, the valves fail to seal correctly, causing compression loss, rough running, increased fuel consumption, and deteriorating engine output. This original replacement is manufactured to original factory specifications, restoring reliable engine performance to your Yamaha NMAX 125 scooter.

Complete Part Guide

Extreme heat inside the combustion chamber can degrade exhaust valve surfaces over time, and this original Yamaha NMAX125 Exhaust Valve x2 Set (2DP-E2121-00) for 2015-2020 models is designed to restore performance. As valve faces wear or burn, sealing efficiency drops, and engine performance becomes inconsistent. This set restores proper sealing and heat-resistant operation, ensuring stable exhaust flow and reliable engine performance. Built to Yamaha's original specifications, it provides precise fitment and dependable durability. In stock now at Part Hive's London hub, order before 1 PM for same-day UK dispatch.

When performance drops, engine breathing is usually affected. Typically, worn exhaust valves restrict how gases exit the chamber, reducing efficiency. In the workshop, we identify this during performance checks or engine inspections. Riders may focus on other systems first. We install this original Yamaha exhaust valve set and it restores proper exhaust flow, ensures a flush and secure fit, and brings the engine back to smooth, consistent performance on your NMAX-125.
