Product Overview

This high-quality Original Pin Piston Ring Circlip Set is designed to meet or exceed factory performance standards and is suitable for Yamaha NMAX 125 (2015-2024) models.

The Pin Piston Ring Circlip Set is a complete piston assembly hardware kit containing the piston pin, piston rings, and retaining circlips required for a full piston rebuild. The piston pin connects the piston to the small end of the connecting rod, the rings seal the combustion chamber and control oil consumption, and the circlips lock the pin laterally in position. When any of these components wear, deform, or are damaged, the result is compression loss, oil burning, piston rattle, or piston pin migration that can cause catastrophic engine damage. This original replacement is manufactured to original factory specifications, restoring reliable performance to your Yamaha NMAX 125 scooter.

Complete Part Guide

Preventing engine damage starts with securing the smallest moving parts. If the piston ring circlips fail, the piston pin or rings can shift or escape, causing internal damage, knocking, or even a seized engine. The original Yamaha NMAX125 Pin Piston Ring Circlip Set (2DS-E1631-99) for 2015-2024 models keeps the piston pin and rings in the correct position, reducing the risk of internal movement and maintaining efficient combustion. Designed to Yamaha's original specifications, it ensures precise installation, reliable retention, and durability under continuous engine stress. Available from Part Hive's London warehouse, order before 1 PM for same-day UK dispatch.

We see this more often than people think, engine damage starting from something small that got overlooked during assembly. Usually, it's a worn circlip that's lost its grip, allowing the piston pin to move and touch parts it shouldn't. We come across it quite a bit when correcting rebuilds. Riders sometimes try to reuse these small bits, but that's where the trouble starts. We fix it with the correct original Yamaha NMAX-125 pin piston ring circlip set, and it puts it right, with a secure hold, no movement, and proper protection inside the engine.
