Product Overview
This high-quality Original Bearing Radial Ball 6301 is designed to meet or exceed factory performance standards and is suitable for Honda PCX125 (2010-2025) models.
The Bearing Radial Ball 6301 is a small-bore precision radial ball bearing with a 12 mm bore, providing rotational support for its corresponding shaft within the engine or drivetrain assembly. The bearing allows smooth, frictionless rotation under the radial loads encountered during normal operation. As the bearing wears, internal play and friction increase, resulting in noise, vibration, and roughness at the bearing location that can escalate into damage to the shaft and housing if not resolved. This original replacement is manufactured to original factory specifications, restoring original bearing precision and reliable engine or drivetrain performance to your PCX125.

Complete Part Guide
The gearbox radial ball bearing on your Honda PCX125 2010-2025 is essential for stabilizing the internal gear shafts under high rotational speeds. If the 6301 bearing begins to wear, it often creates a persistent metallic whirring or "droning" noise that emanates from the rear of the transmission case. This original Honda part (91005-KZR-602) is manufactured to specific clearances required for the PCX's oil-bath environment. Physically held at Part Hive's London warehouse, order before 1 PM for guaranteed same-day UK dispatch.
We often encounter Honda PCX-125 2010-2025 models with significant gearbox vibration caused by a failed 91005-KZR-602 bearing, usually resulting from high-mileage fatigue or infrequent gear oil changes. If you notice a "gritty" sensation when rotating the rear wheel or hear a growl that changes with speed, the internal races are likely pitted. In our experience, using standard industrial bearings here is a risky shortcut that often leads to premature failure because they aren't rated for the specific lateral thrust of the Honda final drive. This original Honda Radial Bearing provides the exact metallurgical hardness and fitment needed to restore a whisper-quiet transmission, replacing noisy, rattling, or collapsed internal gearbox bearings.
