Product Overview

This high-quality Original Gear Box Bearing 6302Z is designed to meet or exceed factory performance standards and is suitable for Yamaha NMAX 125 (2015-2025) models.

The gear box bearing is a precision single-shielded deep-groove ball bearing that supports the rotating shaft within the final drive gearbox, carrying radial and axial loads while enabling smooth, low-friction shaft rotation. Bearing wear, contamination, or lubricant breakdown generates audible noise from the gearbox area, introduces shaft play, and increases wear rates on the mating gears and housing bore, reducing drivetrain efficiency over time. This original replacement is manufactured to original factory specifications, restoring correct shaft support and quiet, reliable gearbox performance on your Yamaha NMAX 125.

Complete Part Guide

Designed for controlled, high-efficiency rotation, this deep groove bearing plays a vital role inside the gearbox. The original Yamaha NMAX125 Gear Box Bearing 6302Z (93306-302YU) for 2015-2025 models ensures smooth movement between components, helping the transmission operate with minimal resistance. Built to Yamaha's original specification, it fits accurately and performs reliably under load. In stock at Part Hive's London warehouse, order before 1 PM for same-day UK dispatch.

We often get NMAX-125s in where the rider thinks there's a gearbox fault. Rough feel, slight noise, maybe some resistance. In the workshop, this is something we see quite a bit, and it usually traces back to the bearing rather than anything major. Riders tend to expect a bigger issue, but it's often just this. We install the correct original Yamaha gearbox bearing and it restores smooth operation, ensures precise alignment, and resolves the issue cleanly.
