Fitment note: Broad search listing only. Use the model-specific listing above and compare the original bearing/race dimensions before ordering.
Steering Bearing Dimensions / Cross-Check
- Upper race outer diameter: approximately 45mm
- Upper steering-stem inner diameter: approximately 26mm
- Lower race outer diameter: approximately 54mm

Common Signs of Worn Steering Head Bearings
- Notchy or indexed feeling as the handlebars pass through the straight-ahead position
- Heavy or uneven steering
- Knocking or movement at the steering head under braking
- Excessive free play at the front end
- Corroded, pitted or damaged bearing races found during front-end servicing
Important Compatibility & Fitting Checks
- Confirm the exact scooter model and production year.
- Compare the upper and lower race diameters with the parts removed from the frame.
- Check the steering-stem diameters and mating cone shapes.
- Inspect the steering-head dust seal and locknut while the front end is dismantled and replace separately if required.
- Apply a suitable high-quality bearing grease during assembly.
- Adjust steering-bearing preload according to the Honda workshop procedure; overtightening can cause heavy steering and premature wear.
Steering bearings are a safety-critical chassis component. Installation should be carried out by someone with suitable motorcycle/scooter repair experience and the correct bearing installation tools.
