The Kriega OS-Base KTM 1050-1290 is a larger, purpose-built version of the renowned OS-Base system, engineered to fit KTM 1050, 1090, 1190 Adventure, and 1290 Super Adventure models perfectly. This over-the-seat harness allows riders to mount OS-6, OS-12, or OS-18 Adventure Packs as soft panniers—no metal racks, drilling, or permanent modifications required.

Constructed from heavy-duty Hypalon with reinforced stitching, the OS-Base is both lightweight and incredibly tough, built to withstand demanding off-road terrain and long-distance travel. The included KTM Rack Loops and alloy spacers provide multiple hook-on points, giving you flexibility to configure one, two, or three OS-Packs for a total capacity of up to 54 liters.

The custom shape ensures a precise, stable fit with generous exhaust clearance, while non-slip cam buckles and aircraft-grade alloy hooks deliver secure and repeatable mounting. The system installs in under a minute and removes in seconds—ideal for everything from technical trail rides to multi-day adventure touring.
