Product Overview

This high-quality Original Bearing Radial Ball 6205UU is designed to meet or exceed factory performance standards and is suitable for Honda PCX125 (2021-2025) models.

The Bearing Radial Ball 6205UU is a sealed radial ball bearing with a 25 mm bore, designed to provide smooth, low-friction rotational support for its corresponding shaft in the engine or drivetrain. The double sealed (UU) construction keeps grease in and contaminants out, ensuring consistent performance throughout the bearing's service life. When the bearing deteriorates, noise, vibration, and increased friction develop at the bearing location, which can escalate into shaft or casing damage if not attended to promptly. This original replacement is manufactured to original factory specifications, restoring original bearing precision and quiet operation to your PCX125.

Complete Part Guide

Transmission drone that builds with engine load rather than road speed points to a failing gearbox bearing. Contaminated gear oil and high mileage are the two most common causes on the PCX. Part No. 91009-K2S-N01 is the original Honda 6205UU radial ball bearing for the Honda PCX125 2021-2025 models, the correct double-seal specification for an oil-bathed final drive. Ready for immediate dispatch from Part Hive's London hub, order before the 1 PM cutoff for guaranteed same-day UK dispatch.

We often see 2021-2025 Honda PCX-125 models coming in with transmission noise caused by the 91009-K2S-N01 bearing failing prematurely after water ingress or gear oil neglect. In our experience, once the internal 6205UU races become pitted, the resulting vibration can cause the gear teeth to wear unevenly, leading to a much more expensive gearbox overhaul. Risky fixes involving open-race industrial bearings often fail because they lack the specific "UU" seal integrity required for this housing's environment. This original Honda Radial Bearing provides the exact sealing and load-bearing capacity needed to restore a whisper-quiet transmission, replacing noisy, gritty, or loose-fitting aftermarket bearings.
