Product Overview

This high-quality Original Cylinder Barrel is designed to meet or exceed factory performance standards and is suitable for Yamaha NMAX 125 (2015-2024) and YZF-R125 (2019-2025) models.

The Cylinder Barrel is the precision-machined bore housing that guides the piston throughout its full stroke, forming the combustion chamber wall and providing a controlled surface for the piston rings to seal against. When the bore wears elliptical, develops deep scoring from oil starvation, piston seizure, or foreign material ingestion, compression drops significantly, oil consumption rises, blue exhaust smoke appears, and the engine loses power and efficiency. This original replacement is manufactured to original factory specifications, restoring reliable performance to your Yamaha motorcycles and scooters.

Complete Part Guide

Right at the centre of the engine, the cylinder barrel forms the combustion chamber the piston moves in, directly shaping compression and combustion efficiency. The original Yamaha NMAX125 Cylinder Barrel (2DS-E1311-10) for 2015-2024 models houses the piston and maintains the compression needed for efficient combustion. When everything here is right, the engine runs smoothly and delivers consistent performance. Built to Yamaha's original standard, it offers precise tolerances, effective heat control, and long-term reliability. Available now from Part Hive's London hub, order before 1 PM for same-day UK dispatch.

When an engine starts losing power, this is one of the first places we think about. Compression leaks aren't easily noticeable; they just slowly take performance away. We've seen riders chase fuel or ignition faults when the issue was sitting right here in the cylinder. We swap it for a proper original Yamaha cylinder barrel, and the difference is immediate: stronger pull, smoother running on your NMAX-125.
