The Adventure Bike OS-Base Combo 12 delivers compact, rackless storage designed to fit most adventure motorcycles. This complete system includes the OS-Base harness and two OS-6 Adventure Packs, providing 12 liters of waterproof capacity for tools, spares, and everyday riding essentials. Built from heavy-duty Hypalon with reinforced stitching and secured by aircraft-grade alloy hardware, it’s ready for demanding conditions, while roll-top closures with removable liners keep your gear protected from rain, dust, and mud.

Designed to fit the vast majority of adventure motorcycles, the OS-Base uses a universal over-the-seat harness that works with bikes equipped with rear racks or passenger grab handles. It mounts using included OS-Rings and Subframe Loops to create multiple secure attachment points, adapting easily to different bike layouts. The system requires no additional frames, brackets, or permanent modifications, making it a flexible solution that can transfer between bikes as your setup evolves.
