Kriega OS-Base Dirtbike Mounting SystemDesigned to fit perfectly on the latest lightweight enduro bikes, with a custom shape and specific mounting hardware. The OS-BASE DIRTBIKE is an ‘over-the-seat harness’ for attaching OS-6, OS-12 or OS-18 Adventure Packs as soft panniers without the need for metal frames or racks. This system provides a super-rugged, lightweight carrying solution that requires only minor body modifications. Matching hardware provides the flexibility to mount a one-, two- or three-pack setup depending on how you ride. Fixed length straps make installation quick and easy, and the custom shape provides a snug, secure fit with plenty of clearance from the exhaust. It takes less than a minute to attach and seconds to remove. The OS-Base is a harness that attaches to the motorcycle seat and allows you to mount Kriega OS-Adventurepacks: OS-6, OS-12 or OS-18. With the addition of the OS-Adventurepack, you have a 100% waterproof, heavy-duty carrying capacity of up to 54 liters of luggage volume. The heavy-duty Hyperlon construction gives the OS-Base extra ruggedness, despite its light weight.Features:Capacity from 12 to 54 liters with center mount optionRugged hypalon constructionQuick and easy to put on and take offReinforced stitching at all stress pointsAircraft alloy hooksNon-slip cam bucklesSpecifications:Compatibility:Kriega Overlander-S OS-6 BagKriega Overlander-S OS-12 BagKriega Overlander-S OS-18 BagContents:1x Kriega OS-Base dirtbike mounting system2x Kriega OS-Dirtbike mounting rings4x Kriega Universal OS Loops mounting rings1x Silicone heat shieldNote:Even though most OS-BASE are mounted on the seat, the sides may rub against the plastic sidewalls of the bike, causing minor abrasion. This can be exacerbated if mud and dust get between the OS-BASE and the plastics. We strongly recommend applying a clear protective film to areas where abrasion may occur on your bike.
