This is a special specification for the Live Dio ZX. It's a 65L type. The inner cushion is also included. I bought it about two years ago. I welded it to the genuine rear carrier, so it won't shift firmly while riding. I've made cuts to accommodate tools for easy attachment and removal. 55L was too small, so I bought the 65L at the time. It might not be available anymore. I calculated it so the seat would barely open, because the center of gravity is shifted to the rear. Since it's within the width of the handlebars, the box won't hit car mirrors or anything else if the handlebars can pass through. It shows signs of use, but I don't think there's any damage.
