Product Overview

This high-quality Original Steering Nut is designed to meet or exceed factory performance standards and is suitable for Yamaha NMAX 155 (2017-2025) models.

The steering nut secures the top of the steering stem within the steering head, maintaining correct preload on the steering bearings and ensuring smooth, precise steering movement. A loose, worn, or damaged nut allows bearing preload to shift, resulting in steering play, vibration through the handlebars, and imprecise directional control. This original replacement is manufactured to original factory specifications, restoring correct steering preload and reliable front-end handling to your Yamaha NMAX 155.

Complete Part Guide

Steering issues can sometimes appear after maintenance if fastening components are no longer holding as they should, something the original Yamaha NMAX 155 Steering Nut (90179-25810) for 2017-2025 models is designed to resolve. Reused or worn nuts may struggle to maintain proper torque. This component ensures secure fastening and consistent clamping, keeping the steering assembly stable and correctly aligned.

You can tell when the front end of a Yamaha NMAX-155 isn't sitting right. It's not always visible, but it feels loose or inconsistent. We've traced that back to the steering nut more than once. It usually loses its ability to hold proper torque. Riders don't expect it to be that small part causing it. We replace it with the original Yamaha steering nut, torque it properly, and the difference is clear: the front end feels tight, controlled, and back to normal.
