- OS-Base Harness (main unit)
- 2 x OS-Dirtbike Rings
- Silicone Heat Shield
- Mounting Hardware (bolts, washers, spacers as required)
- Zip ties (for securing excess straps)
Installation Steps:
- Prepare the Motorcycle: Ensure the rear fender and side panels are clean and free of debris. Identify suitable mounting points on the rear fender for the OS-Dirtbike rings. These are typically existing bolt holes or strong, flat surfaces.

- Attach OS-Dirtbike Rings: Secure the two OS-Dirtbike rings to the rear fender using the provided hardware. Ensure they are firmly tightened and positioned symmetrically.
- Position the OS-Base: Drape the OS-Base harness over the rear seat and fender of the motorcycle. The main body of the OS-Base should sit on the rear fender, with the side panels extending down along the side of the bike.

- Secure Front Straps: Locate the front straps of the OS-Base. These straps typically loop around the subframe or a secure point near the footpegs. Use the quick-attach aircraft grade alloy hooks to secure them. Adjust the cam buckles to pull the OS-Base forward and snug against the bike.

- Connect Rear Straps: Connect the rear straps of the OS-Base to the previously installed OS-Dirtbike rings on the fender. Use the quick-attach hooks and adjust the cam buckles to pull the OS-Base rearward, ensuring a tight fit.

- Install Silicone Heat Shield: If your exhaust pipe is in close proximity to the OS-Base or mounted luggage, install the silicone heat shield on the exhaust to prevent heat damage to the system and its contents.
- Final Adjustments: Ensure all straps are taut and the OS-Base is securely mounted without any excessive movement. Trim any excess strap length and secure with zip ties or strap tidies to prevent flapping during riding.

Operating Instructions
The OS-Base is designed for modularity, allowing you to attach various Kriega OS-Packs (sold separately) to suit your storage needs.
Attaching OS-Packs:
- Side Packs: OS-Packs (e.g., OS-6, OS-12, OS-18) can be attached to the side panels of the OS-Base using the integrated loops and straps. Ensure the packs are balanced on both sides to maintain motorcycle stability.

- Top Pack: A larger OS-Pack or roll-top bag can be mounted on top of the OS-Base using the central pack mounting option, allowing for adjustable carrying capacity from 12 to 54 liters depending on the combination of packs.

- Securing Packs: Use the compression straps and buckles on the OS-Base and OS-Packs to cinch down the luggage tightly. This prevents shifting during riding and maintains a low center of gravity.

Maintenance
Regular maintenance will extend the lifespan of your Kriega OS-Base Dirtbike system.
- Cleaning: Clean the Hypalon and nylon surfaces with mild soap and water. Use a soft brush to remove stubborn dirt. Rinse thoroughly and allow to air dry completely before storage. Do not use harsh chemicals or abrasive cleaners.
- Inspection: Periodically inspect all straps, buckles, and stitching for signs of wear, fraying, or damage. Check the integrity of the Hypalon material for any tears or punctures.
- Hardware Check: Ensure all metal hardware (hooks, buckles, OS-Dirtbike rings, and mounting bolts) are free from corrosion and are securely fastened. Tighten any loose bolts as necessary.
- Storage: Store the OS-Base in a cool, dry place away from direct sunlight when not in use.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| OS-Base feels loose or shifts during riding. | Straps not sufficiently tightened; incorrect routing of straps. | Re-check all strap connections and cam buckle adjustments. Ensure straps are routed correctly around the subframe and through the OS-Dirtbike rings. Cinch down all straps firmly. |
| Luggage shows signs of heat damage. | Proximity to exhaust pipe; heat shield not installed or improperly positioned. | Ensure the silicone heat shield is correctly installed on the exhaust pipe. Adjust luggage position if possible to increase clearance. Consider additional heat protection if necessary. |
| Difficulty attaching OS-Packs. | Incorrect alignment; straps tangled. | Ensure the OS-Packs are oriented correctly. Untangle straps and align buckles before attempting to connect. Refer to OS-Pack specific instructions for attachment. |
