Designed to be a perfect fit on the DUCATI DESERT-X with a custom shape and specific fitting hardware. The OS-BASE 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. This system provides a super-tough, lightweight carrying solution, with no bodywork alterations needed. The fitting hardware gives the flexibility to mount a one, two, or three-pack set-up, depending on your type of 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. The New X-STRAPS provide extra pack stability for heavy loads or extreme off-road riding. It takes less than a minute to mount and just seconds to remove it.
