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 Vision 110 (2017-2020) 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 Vision 110.

Complete Part Guide
The 91003-KZR-601 Crankcase Gearbox Bearing Radial Ball is a specialized 6204-spec component that supports the internal gear shafts within the Honda Vision110 crankcase. For the 2017-2020 models, this original Honda part is essential for ensuring that the transmission gears mesh with microscopic precision. Without a high-grade bearing, the shaft can begin to oscillate, leading to rapid gear wear and potential oil seal failure. To maintain your vehicle's mechanical integrity, secure this component from Part Hive's London warehouse; complete your order before 1 PM for guaranteed same-day UK dispatch.
We often identify failures in the Honda Vision-110 (2017-2020) transmission when we hear a distinct "whining" or "grinding" sound that changes pitch with the scooter's speed. In our experience, this is usually a fatigued 91003-KZR-601 6204 bearing that has developed excessive axial play. This original Honda replacement is critical because the 6204 spec used here must tolerate constant immersion in gear oil while resisting the contaminants that settle at the bottom of the case. Replacing this bearing during a standard transmission refresh prevents the gear teeth from developing "pitting" caused by an unstable shaft.
