Introduction
This manual provides detailed instructions for the proper installation, operation, and maintenance of the Givi SR2139 Rear Rack Adapter. This adapter is specifically designed for the Yamaha Tracer 900 and 900 GT models (2018-2019) to facilitate the mounting of Givi MONOLOCK or MONOKEY top case plates.
Please read these instructions thoroughly before beginning installation to ensure correct assembly and safe use of the product.
Package Contents
The Givi SR2139 kit includes all necessary components for mounting the rear rack adapter to your motorcycle. Please verify that all parts listed below are present before proceeding with installation.

Image 1: All components of the Givi SR2139 Rear Rack Adapter kit. This includes various black metal brackets, an arched support bar, and a comprehensive set of bolts, washers, and spacers required for installation.
The kit typically contains:
- Main support brackets
- Crossbar/reinforcement bar
- Mounting plates/supports
- Assorted bolts, washers, and spacers
Note: Givi MONOLOCK or MONOKEY adapter plates (e.g., M5, M7, M8A, M8B, M9A, M9B, M5M, M6M) and the top case itself are sold separately and are required for a complete luggage system.
Setup and Installation
Installation of the Givi SR2139 Rear Rack Adapter requires basic mechanical skills and tools. It is recommended to have the motorcycle on a stable stand during installation.
- Preparation: Ensure the motorcycle is turned off and stable. Remove any existing rear rack components or passenger grab handles as instructed by your motorcycle's service manual, if necessary.
- Initial Placement: Position the main support brackets onto the designated mounting points on the rear of the motorcycle. These points are typically located near the passenger seat or tail section.
- Secure Main Brackets: Use the provided bolts and washers to loosely secure the main support brackets. Do not fully tighten at this stage.
- Install Crossbar: Attach the arched crossbar or reinforcement bar between the main support brackets, aligning the holes. Secure with the appropriate bolts and washers, again, only hand-tightening for now.
- Mount Adapter Plate Supports: Attach the smaller mounting plates or supports that will eventually hold the Givi top case adapter plate. These typically connect to the main support brackets.
- Final Alignment and Tightening: Once all components are in place and loosely assembled, ensure proper alignment. The rack should be centered and level. Systematically tighten all bolts to the manufacturer's specified torque settings. Refer to your motorcycle's service manual for specific torque values for frame-mounted components if Givi does not provide them.
- Adapter Plate Installation: Once the SR2139 adapter is securely installed, you can then mount your chosen Givi MONOLOCK or MONOKEY adapter plate (sold separately) onto the SR2139. Follow the instructions provided with your specific Givi adapter plate.
Important Note: If you are using Givi adapter plates M8A, M8B, M9A, or M9B, the assembly of a stop light kit or a remote control device on the top case may not be possible due to design constraints with the SR2139 adapter.
Operating Instructions
The Givi SR2139 Rear Rack Adapter provides a secure base for Givi MONOLOCK or MONOKEY top case plates. Once the appropriate adapter plate is installed, you can attach and detach your Givi top case.
- Attaching a Top Case: Align the top case with the adapter plate and press down until it clicks securely into place. Ensure the case is locked to prevent accidental detachment.
- Detaching a Top Case: Use the release mechanism on your Givi top case (typically a button or lever) to unlock and remove the case from the adapter plate.
- Weight Capacity: Always adhere to the maximum weight capacity specified by Givi for both the rack adapter and your specific top case. Overloading can compromise stability and safety.
Maintenance
Regular maintenance ensures the longevity and safe operation of your Givi SR2139 Rear Rack Adapter.
- Regular Inspection: Periodically check all bolts and fasteners for tightness. Vibrations from riding can cause components to loosen over time.
- Cleaning: Clean the rack adapter with mild soap and water. Avoid harsh chemicals or abrasive cleaners that could damage the finish.
- Corrosion Prevention: If riding in wet or corrosive conditions, inspect the rack for signs of rust or corrosion. Apply a suitable protective spray if necessary.
- Damage Check: In case of an accident or impact, thoroughly inspect the rack adapter for any bends, cracks, or damage. Replace damaged components immediately.
Troubleshooting
- Loose Rack: If the rack feels loose, re-check all mounting bolts and ensure they are tightened to the correct torque specifications.
- Difficulty Attaching Top Case: Ensure the Givi adapter plate is correctly installed and free from obstructions. Check for any debris in the locking mechanism.
- Unusual Noise: Rattling or unusual noises often indicate loose components. Stop and inspect all fasteners and connections.
