Product Overview

This high-quality Original Gear Box Bearing 6303 is designed to meet or exceed factory performance standards and is suitable for Yamaha NMAX 125 (2015-2025) models.

The gearbox bearing supports the rotating shafts within the transmission housing, reducing friction and maintaining precise shaft alignment during power delivery. A worn or failed bearing causes increased transmission noise, vibration during acceleration, excessive heat build-up in the gearbox, and eventual shaft misalignment that accelerates gear component wear. This original replacement is manufactured to original factory specifications, restoring smooth and efficient transmission operation to your Yamaha NMAX 125.

Complete Part Guide

The real test of a transmission is how it performs under pressure. If this gearbox bearing weakens, the transmission can feel notchy, develop clunking noises under load, and suffer accelerated wear on shafts and gears. The original Yamaha NMAX125 Gear Box Bearing 6303 (93306-303YP) for 2015-2025 models supports stable rotation when the drivetrain is under load, reducing internal stress and maintaining smooth power delivery. Manufactured to Yamaha's original standard, it offers precise fitment, consistent performance, and durability where it matters most. Available from Part Hive's London warehouse, order before 1 PM for same-day UK dispatch.

A lot of riders come in thinking it's the engine or CVT, but it turns out to be the gearbox bearing. Once it's worn, it affects how the shafts spin inside. It's not always obvious straight away, which is why it gets missed. We spot it during proper inspections. We replace it with the correct original Yamaha NMAX-125 gearbox bearing, and it sorts it, smooth again, properly aligned, and everything sitting flush like it should.
