The bags are made of heavy, waterproof Iparex 1100. Grips and straps are made of leather. The backside is constructed from a hard, rigid, 4mm thick HDPI plate, to which the "Click & Lock" system is attached. At the inside, the bags are reinforced with PVC. This system allows K - Drive HC bags to be clicked to the specially designed saddlebag holders. They can easily be mounted and removed in seconds. This click system can be locked with a key by means of a lock at the inside of the bag. Both bags use the same key. The saddlebags are model specific and are supplied as a kit, containing 1 pair of saddlebags, 1 pair of saddlebag guards and 2 keys. The "Click & Lock" system has many advantages: The bags are easily mounted and removed in just a few seconds. The bags themselves are locked to the motorcycle with a key. The bags don't touch the motorcycle and therefore don't damage it. They can also be attached to motorcycles that don't have a dual saddle. As the bags are made specifically (or adapted) for a model, every bag perfectly fits each type of motorcycle it is designed for. The saddlebag holders are discreet, following the contour of the motorcycle, and are perfectly chromed. Dimensions : 50cm x 30 x 16cm Capacity : 49LK-Drive
