The Tusk Aluminum Pannier Boxes are designed and manufactured to handle the most extreme adventure motorcycling. These panniers are loaded with features to offer an unbeatable value! These panniers are made from durable yet lightweight aluminum with a tough silver or black powder-coated finish. Not only do they look great, but they prevent the items you store from getting the black residue produced when rubbed against unfinished aluminum. Unique design that eliminates seams on the back two vertical edges (weak spots on other panniers), and all existing welded seams are reinforced with internal stitch welds. For security and convenience, the boxes come complete with 4 (2 on each box) matched locks and keys already assembled on the latches! A rubber gasket at the top of the box ensures the lid is tight and waterproof. Each lid comes complete with 4 bolt-on footman loops to secure additional items. Each Large box is 37 Liters and measures 15 ½ tall, 9 ¼ deep, and 18 wide. The Medium boxes are 27 Liters each and measure 14 ¼ tall, 7 ½ deep, and 16 ¼ wide. Both are sold in pairs.
