Product Overview

This high-quality Original Crankcase Gearbox Bearing Radial Ball 6204 is designed to meet or exceed factory performance standards and is suitable for Honda PCX 125 (2012-2025) models.

The Crankcase Gearbox Bearing Radial Ball 6204 is a precision radial ball bearing housed within the crankcase gearbox assembly, supporting the gearbox shaft and allowing it to rotate smoothly under the transmission loads generated during normal operation. As the bearing wears, increased internal play and friction cause roughness and noise from the gearbox area, degraded transmission smoothness, and, if not addressed, can accelerate wear on the gearbox shaft and casing. This original replacement is manufactured to original factory specifications, restoring gearbox bearing precision and smooth, reliable transmission operation to your PCX 125.

Complete Part Guide

A healthy final drive depends on stable shaft support within the gearbox of the Honda PCX125 (2012-2025). This original Honda Crankcase Gearbox Bearing (6204 HB6204) replaces worn or noisy bearings that can develop roughness, play, or vibration over time. Restoring proper bearing condition helps maintain smoother rotation of the transmission components under load. Orders placed before 1 PM are processed for same-day dispatch from Part Hive's London warehouse.

We regularly encounter Honda PCX-125 2012-2025 scooters with a low-frequency rumble or persistent whirring from the rear drivetrain area, often linked to wear in the 6204 gearbox bearing. In many cases, contamination or long service intervals can lead to pitting on the bearing surfaces, which gradually introduces vibration into the final drive system. If left unchecked, this can increase stress on nearby seals and gears. Replacing it with original Gearbox Bearing Radial Ball 6204 HB6204 restores smoother rotation and helps maintain reliable gearbox operation under normal riding conditions.
