Installation Steps:
- Preparation: Ensure the motorcycle is securely supported on a stand, and the front wheel is off the ground.
- Disassembly: Carefully remove the steering stem nut and any existing washers or components as per your motorcycle's service manual.
- Placement: Position the Genuine Honda Steering Stem Washer (Part No. 90503-283-000) directly under the steering stem nut. Ensure it sits flat and correctly aligned on the steering stem.

4. Maintenance
While the steering stem washer is a durable component, periodic inspection is recommended to ensure its longevity and the safety of your motorcycle.
- Cleaning: If removed during other maintenance, clean the washer with a soft cloth to remove any dirt or debris before reinstallation.
- Inspection: During routine maintenance of your motorcycle's front end, inspect the washer for any signs of wear, corrosion, deformation, or cracks. Replace the washer if any damage is observed.
- Lubrication: Ensure that the area where the washer sits is properly lubricated as specified by your motorcycle's service manual to prevent premature wear and ensure smooth operation.

If you experience issues related to the steering stem assembly after installation, consider the following:
- Steering Play: If there is excessive play in the steering, re-check the torque of the steering stem nut. Ensure the washer is correctly seated and not damaged.
