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 125 (2015-2025) 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 125.

Complete Part Guide

If the gearbox bearing fails, the transmission can develop grinding, play, or rough engagement, which harms both feel and long-term reliability. The original Yamaha NMAX125 Gear Box Bearing 6301 (93306-351Y8) for 2015-2025 models supports rotating components inside the transmission, reducing friction and keeping power delivery clean and efficient. When it's right, everything feels effortless. Built to Yamaha's original standard, it delivers precise fitment, smooth operation, and dependable durability under load. Available from Part Hive's London warehouse, order before 1 PM for same-day UK dispatch.

If you're hearing a whining noise from the transmission, especially when you're on the throttle, it's usually the bearing. Once it wears, it won't run smoothly anymore. We see this all the time on higher-mileage NMAX-125 bikes. Riders often leave it at first, but it never gets better. We replace it with the correct original Yamaha gearbox bearing, and it sorts it, quiet again, smooth rotation, and everything running as it should.
