The OS-Base is an ‘over the seat harness’ which allows OS-6, OS-12, or OS-18 Adventure Packs to be mounted as soft panniers. No heavy metal frames are required, this system provides a super-tough, lightweight carrying solution for the CRF 1100L with no permanent bodywork alterations to the bike.

The modular design enables you to modify your luggage set-up to suit your ride – from a single-day ride-out to longer moto-camping adventure trips.

The CRF bolt-on loops included attach to the bike frame under the seat and fit behind the CRF alloy mounts to provide 4 hook-on 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 3 or more bag set-up, or can be used to mount an OS-Pack as a stand-alone tail pack without the OS-Base.

The set length straps make mounting a breeze and the purpose-designed main body shape provides a tight, secure fit with plenty of distance from the exhaust. It takes less than a minute to mount the system to the bike and just seconds to remove it.

NOTE: Due to the rear rack added as standard on the latest 2022 models the OS-Base system will not fit these bikes.

Even though most of the OS-BASE mounts on the seat, the sides can rub against the plastic side panels of the bike, resulting in minor abrasion. This can be further exaggerated if mud and dust get in between the OS-BASE and the plastics. We strongly recommend applying a clear adhesive protective sheet to where abrasion may occur on your motorcycle.
