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 150 (2017-2023) 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 150.

Complete Part Guide

Fork oil leaks don't just affect performance; they can become a safety issue, and that's exactly what the original Yamaha NMAX150 Front Shocks Oil Seal X2 Set (3HB-F3145-00) is designed to prevent for 2017-2023 models. Once oil escapes, damping drops off and can even spread onto other components. This set restores a proper seal, keeping oil where it should be and the suspension working consistently. Built to Yamaha's standards, it fits right and seals properly. Available now from Part Hive's London hub, enjoy same-day UK dispatch on all orders completed before 1 PM.

We've had Yamaha NMAX-150 bikes come in with oil traced down the fork leg, sometimes even reaching near the brake area. That's a clear sign the seal has failed. Once oil leaves the fork, damping drops straight away. It also becomes a safety issue if it spreads further. We don't patch these, we replace both seals. We install the correct original Yamaha front shocks oil seal x2 set, and it keeps everything where it should be, inside the fork, doing its job properly.
