4. Setup and Installation
The GIVI Monolock top case requires a rear luggage rack on your motorcycle or scooter for installation. If your vehicle does not have one, a compatible rack must be installed first (sold separately).
4.1. Installing the Universal Plate
- Identify a suitable position on your vehicle's rear luggage rack for the universal plate. Ensure it does not obstruct the rider or passenger, and allows for proper opening of the top case.
- Use the provided universal fitting kit (brackets, screws, washers) to securely attach the plate to the luggage rack. Follow the specific instructions provided with the fitting kit for your vehicle type.
- Tighten all fasteners firmly, but do not overtighten. Periodically check the tightness of the fasteners, especially after the first few rides.
4.2. Attaching the Top Case
- Align the bottom of the top case with the universal plate, ensuring the locking mechanism on the case engages with the plate.
- Press down firmly until you hear a click, indicating the case is securely locked onto the plate.
- Verify the case is securely attached by gently pulling upwards. It should not lift off the plate.
- To remove the top case, insert the key into the lock, turn it, and press the release button (usually located near the lock) while lifting the case.

6. Maintenance and Care
- Cleaning: Clean the top case with mild soap and water. Avoid abrasive cleaners or solvents that could damage the plastic or painted surfaces. Use a soft cloth for drying.
- Lock Mechanism: Periodically lubricate the lock mechanism with a small amount of graphite powder or a silicone-based lubricant to ensure smooth operation.
- Fasteners: Regularly check all mounting fasteners for tightness, especially after long rides or off-road use.
- Storage: When not in use, store the top case in a cool, dry place away from direct sunlight to prevent material degradation.
7. Troubleshooting
- Case not locking onto plate: Ensure the universal plate is correctly installed and not obstructed. Check for any debris in the locking mechanism. Apply light lubricant if stiff.
- Lid not closing properly: Verify that no items inside the case are obstructing the lid. Check the hinges for damage or misalignment.
- Excessive vibration/noise: Ensure the top case is securely mounted to the plate and the plate is tightly fastened to the luggage rack. Reduce heavy loads if necessary.
