Kriega | OS-Base Dirtbike 

Designed to be a perfect fit on the latest lightweight enduro bikes with a custom shape and specific fitting hardware.

The OS-Base Dirtbike is a custom-fit, over-the-seat harness for mounting OS-6, OS-12, or OS-18 Adventure Packs as soft panniers on lightweight enduro bikes—no metal frames needed. This tough, lightweight system allows for flexible one, two, or three-pack setups and quick installation with minimal bodywork changes. The set-length straps and custom shape ensure a secure fit, keeping the packs away from the exhaust. Mounts in under a minute, and removes in seconds.

BODYWORK DAMAGE DISCLAIMER 
Even though most of the OS-BASE mounts on the seat, the sides can rub against the plastic side panels of the bike, resulting in minor abrasion. This can be further exaggerated if mud and dust get in between the OS-BASE and the plastics. We strongly recommend applying a clear adhesive protective sheet to where abrasion may occur on your motorcycle.
