Introduction
This manual provides essential instructions for the proper installation, operation, and maintenance of your Givi Trekker Outback Monokey 58L Aluminum Top Case. Designed for motorcycle use, this robust 58-liter top case offers secure storage with a maximum load capacity of 10 kg. Please read these instructions carefully before using the product to ensure safety and optimal performance.
Setup
The Givi Trekker Outback Monokey top case requires a compatible Givi Monokey mounting plate (sold separately) for installation on your motorcycle. Ensure you have the correct plate for your specific motorcycle model.
- Mounting Plate Installation: Follow the instructions provided with your Givi Monokey mounting plate to securely attach it to your motorcycle's luggage rack. Ensure all bolts are tightened to the manufacturer's specifications.
- Attaching the Top Case: Align the front hooks of the top case with the corresponding slots on the Monokey plate. Press down firmly on the rear of the top case until you hear a click, indicating it is securely latched. Verify the case is firmly attached by gently pulling upwards.
- Locking the Case: Insert the key into the lock cylinder and turn it to the locked position. Remove the key. This secures the case to the mounting plate and prevents unauthorized opening.

Operating
The Givi Monokey system allows for easy opening, closing, and detachment of the top case.
- Opening the Case: Insert the key into the lock and turn it to the unlock position. Press the release button (usually located near the lock cylinder) to unlatch the lid. The lid will then open upwards.
- Closing the Case: Lower the lid until it clicks shut. Ensure it is fully closed to maintain water resistance. For security, turn the key to the locked position and remove it.
- Detaching the Case from the Motorcycle: With the case unlocked, insert the key and turn it to the position that allows the release lever (often a red button or lever) to be activated. Press this lever while simultaneously lifting the top case from the mounting plate.
- Capacity: The 58-liter capacity is designed to accommodate two full-face helmets or a significant amount of luggage, with a maximum weight of 10 kg. Distribute weight evenly to maintain motorcycle stability.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your top case.
- Cleaning: Clean the aluminum surfaces with a mild soap and water solution. Avoid abrasive cleaners or solvents that could damage the finish. Rinse thoroughly and dry with a soft cloth.
- Lock Mechanism: Periodically lubricate the lock cylinder and key mechanism with a graphite-based lubricant or a specialized lock spray to ensure smooth operation.
- Seals: Inspect the rubber seals around the lid for any signs of wear or damage. Intact seals are crucial for maintaining the case's water resistance. Replace if necessary.
- Mounting Hardware: Regularly check all mounting bolts and fasteners on both the top case and the mounting plate for tightness. Vibrations from riding can loosen hardware over time.
