The OS-BASE is an "over-the-seat harness" that allows the OS-6, OS-12 or OS-18 ADVENTURE PACKS to be mounted like soft saddlebags. No heavy metal frame required, this system offers an ultra-strong, lightweight transport solution for the CRF 1100L without any permanent modifications to the motorcycle''s bodywork.
Modular design lets you change the configuration of your luggage to suit your journey - from a day trip to longer adventure motorcycle camping trips.
The included CRF BOLT-ON buckles attach to the motorcycle frame under the seat and fit behind CRF alloy brackets to provide 4 attachment points for a stand-alone OS-PACK or US-Drypack. Used in conjunction with the additional loops on the OS-BASE, they provide various mounting points for a configuration of 3 or more bags, or can be used to mount an OS-PACK as a stand-alone backpack without an OS-BASE.
Fixed-length straps make mounting easy, and the specially designed main body shape offers a tight, secure fit with plenty of clearance from the exhaust. It takes less than a minute to mount the system on the motorcycle, and a few seconds to remove it.
