ZTechniks extremely versatile 4-liter rear storage compartment is a great addition or alternative to the standard tank bag. Besides its cavernous main compartment, four zippered storage areas (three main areas and one document holder) are attached to a cleverly designed, removable tray. A Velcro hinge makes removal of the tray a snap.Sturdy double zippers keep everything secured inside while the pods web straps and rubber coated hooks attach it to the bike. Thinking ahead, ZTechnik included plenty of length in the web straps to make mounting the bag under the seat, to the rear tail cowling, or through a rack an easy process.. Web straps have vinyl coated hooks to prevent sratching or scuffing your motorcycle’s finish. Dimesions: H: 4.5-6 in. W: 9-12.5 in. L:13.75 in.
