Rugged Hypalon construction Quick & easy to mount or remove Reinforced stitching at all stress points Aircraft alloy hooks Non-slip cam buckles Bags not included Suitable for Honda CRF 300L Honda CRF 300 Rallye Kriega OS The KRIEGA OVERLANDER SYSTEM (OS): an innovative pannier system, modular in design. The OS-BASE is a harness that attaches to the motorcycle seat & allows the installation of KRIEGA OS-Adventurepacks: OS-6, OS-12 or OS-18. With the additional 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 a special robustness, despite its low weight. Note 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 & dust get between the OS-BASE & the plastics. We strongly recommend applying a clear protective film to areas where abrasion may occur on your bike.
