Product Overview

This high-quality Original Gear Box Bearing 6301 is designed to meet or exceed factory performance standards and is suitable for Yamaha NMAX 150 (2017-2025) models.

The gear box bearing is a precision deep-groove ball bearing supporting the shaft assembly within the final drive gearbox, carrying the radial and axial loads generated during normal riding while allowing smooth, low-friction rotation. Wear, contamination, or lubricant breakdown within the bearing races produces audible noise from the gearbox, increased shaft play, and progressive deterioration of adjacent gear teeth and housing surfaces. This original replacement is manufactured to original factory specifications, restoring correct shaft support, reducing rotational friction, and ensuring reliable gearbox operation on your Yamaha NMAX 150.

Complete Part Guide

Inside the gearbox, precision matters, because a badly supported bearing can induce vibration, noise, and accelerated wear right through the entire geartrain. The original Yamaha NMAX150 Gear Box Bearing 6301 (93306-351Y8) for 2017-2025 models ensures stable and consistent rotation, supporting smooth transmission operation under load. It plays a key role in maintaining efficient power delivery and reducing internal wear. Built to Yamaha's original specification, it fits correctly and performs reliably over time. Available now from Part Hive's London hub, order before 1 PM for same-day UK dispatch.

A common issue we see is noise coming from the drivetrain, usually a grinding or rough feeling when the bike is moving. In the workshop, this often points to a worn gearbox bearing. It wears out over time from load and heat, especially if lubrication isn't ideal. Riders sometimes think it's something bigger, but it comes back to this. We replace it with this original Yamaha gearbox bearing 6301 for your NMAX-150 and it restores smooth rotation, fits properly in place, and keeps everything running quietly again.
