Designed to be a perfect fit on the HONDA CRF300L & CRF300 RALLY with a custom shape and specific fitting hardware.
The OS-BASE CRF300 is an ‘over the seat harness’ for mounting OS-6, OS-12, or OS-18 ADVENTURE PACKS as soft panniers, with no need for metal frames or racks.
This system provides a super-tough, lightweight carrying solution, with no drilling or permanent bodywork alterations needed.

The fitting hardware gives the flexibility to mount a one, two, or three-pack set-up, depending on your ride.
The set-length straps make mounting quick and easy, and the custom shape provides a tight, secure fit with plenty of distance from the exhaust. It takes less than a minute to mount and just seconds to remove it.
