The OS-BASE is an 'over-the-seat harness' for mounting OS-6, OS-12, or OS-18 ADVENTURE PACKS as soft panniers. This Universal Fit system for trail, enduro or dual-sport bikes, needs no metal frames or racks to attach to, with only slight bodywork alterations needed. The flexible design of the OS-BASE also enables you to mount an extra OS-ADVENTURE PACK, OS-BOTTLE or a US-DRYPACK as a centre pack and includes ‘Loop Mounts' to attach a tent or sleeping mat with the addition of OS-CAM STRAPS or OS-MINI CAM STRAPS.

After the initial set-up it’s quick and easy to put on and take off, and the heavy-duty Hypalon construction with a semi rigid polypropylene core is very stable and lightweight. The unique OS-RACK LOOP mounting system provides a very tough and reliable solution to the demands of off-road luggage carrying.


  • Carrying capacity from 12 to 54 litres (luggage sold separately)
  • Heavy-duty Hypalon construction
  • Quick and easy to put on/take off
  • Reinforced stitching on all stress points
  • Aircraft-grade alloy hooks
  • Non-slip cam buckles
  • Includes 2x OS-RACK LOOPS (require 2x 6mm holes drilled in the rear fender for fitting)
  • Weight: OS-BASE + fitting kit 700g
  • 10-year guarantee against defects in materials and manufacture

NB: If the OS-BASE is in contact with the exhaust silencer you must fit a heat shield. 

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. Kriega strongly recommend applying a clear adhesive protective sheet to where abrasion may occur on your motorcycle.
