Product Overview

This high-quality Original Complete Cylinder Barrel Piston Ring Kit is designed to meet or exceed factory performance standards and is suitable for Yamaha NMAX 125 (2015-2020) models.

The Complete Cylinder Barrel Piston Ring Kit combines the precision-machined cylinder barrel and a full set of piston rings into a single top-end rebuild package, providing every component needed to restore the engine bore and piston-ring seal in one supply. When the cylinder bore wears elliptical, develops scoring or seizure marks, and the rings lose their tension, compression drops sharply, oil consumption rises, power output falls, and the engine becomes prone to overheating. This original replacement is manufactured to original factory specifications, restoring reliable performance to your Yamaha NMAX 125 scooter.

Complete Part Guide

Internal engine wear doesn’t stay isolated; it spreads. Scoring in the cylinder and worn piston rings reduce sealing, leading to power loss, higher oil consumption, and unstable combustion. The original Yamaha NMAX125 Complete Cylinder Barrel Piston Ring Kit (2DP-E1311-99) for 2015–2020 models addresses this completely by replacing all top-end components together, restoring clean contact surfaces and proper compression. Engineered to Yamaha’s original standards, it ensures accurate fitment and reliable long-term durability. Available from Part Hive's London warehouse, order before 1 PM for same-day UK dispatch.

A lot of rebuilds fail because only half the job gets done. We've seen cases where just the rings are replaced, but the cylinder is already worn, or vice versa. It might run better for a short time, but the mismatch causes problems again. In proper workshop practice, these components are treated as one system. We install this original Yamaha NMAX-125 complete cylinder barrel piston ring kit, we're not guessing tolerances or mixing wear levels. Everything fits as intended, sits flush, and restores the engine to a proper baseline, exactly how it should be after a rebuild.
