The OS-Base Honda CRF 1100L is a purpose-built over-the-seat harness that allows you to mount OS-6, OS-12, or OS-18 Adventure Packs as soft panniers, all without the need for heavy metal frames. This lightweight, durable system is designed specifically for the CRF 1100L, requiring no permanent modifications to the bike. Its modular design offers flexibility, making it ideal for everything from quick day rides to long moto-camping trips. 

The included CRF bolt-on loops securely attach under the seat and behind the alloy mounts, providing four reliable hook-on points for your OS-Pack or US-Drypack. With additional loops on the OS-Base itself, you can create a variety of configurations, such as a 3-bag setup or a standalone tail pack. 

Set-length straps make for a quick, hassle-free mounting process, and the system is designed for a tight, secure fit with plenty of clearance from the exhaust. Installation takes under a minute, and removal is just as fast, making it the perfect solution for riders seeking versatility and ease.
