Product Overview

This high-quality Original Front Shocks Oil Seal X2 Set 30X40.5X10.5 mm is designed to meet or exceed factory performance standards and is suitable for Yamaha NMAX 125 (2015-2025) models.

The front fork oil seals form a critical barrier around each fork stanchion, retaining fork oil and preventing road contamination from entering the damping system. Worn or deteriorated seals allow fork oil to leak down the stanchion, reducing damping effectiveness and causing the forks to feel harsh, inconsistent, and unresponsive, particularly under braking and over uneven surfaces. This original replacement set is manufactured to original factory specifications, restoring effective fork sealing and consistent front suspension performance to your Yamaha NMAX 125.

Complete Part Guide

Oil loss within the fork assembly isn't always immediately visible, and this original Yamaha NMAX125 Front Shocks Oil Seal X2 Set (3HB-F3145-00) for 2015-2025 models is designed to prevent that from happening. Even minor leakage can reduce suspension efficiency over time. This component ensures a tight seal, keeping fork oil contained and maintaining consistent damping performance. Manufactured to the original Yamaha specification, it ensures exact fitment and dependable durability. Available now from Part Hive's London hub, enjoy same-day UK dispatch on all orders completed before 1 PM.

Not every Yamaha NMAX-125 comes in with oil dripping down the fork. Sometimes it's just a small loss over time that riders don't notice. We've checked forks that feel off, only to find the seals aren't holding properly anymore. That slight oil loss changes how the fork reacts. It's subtle but affects control. We replace it with the original Yamaha front shocks' oil seal set, and it brings everything back to proper oil level, consistent movement, and stable handling again.
