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 155 (2020-2024) 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 155.

Complete Part Guide

Consistent suspension performance depends on both fork sides operating equally, something the original Yamaha NMAX155 Front Shocks Oil Seal X2 Set (3HB-F3145-00) for 2020-2024 models is designed to ensure. Uneven sealing can cause imbalance and affect handling. This matched set restores equal sealing on both sides, maintaining proper oil retention and stable damping performance. Manufactured to original Yamaha specification, it delivers exact fitment and dependable long-term use. In stock now at Part Hive's London hub, order before 1 PM for same-day UK dispatch.

Forks on the Yamaha NMAX-155 rely on sealed oil pressure to control movement. Once the seal starts to fail, that pressure drops. We've seen forks where one side loses pressure faster, creating an imbalance across the front. It's not just about leaks; it's about performance loss. During servicing, we replace seals in pairs to keep both sides equal. We replace it with the correct original Yamaha front shocks oil seals set, and it restores proper pressure inside the fork, consistent damping, and no imbalance.
