Increase your storage capacity, improve the appearance, and optimize your topcase setup with this Touratech Topcase Lid Bag.  This item was specifically designed for the Vario topcase found on the R1300GS, but it will also fit nicely on Touratech Zegas, or some competing boxes as well.

This lid bag is characterized by elegant design, and thoughtful practicality. It's held securely in place with four velcro straps, and doesn't have a significant impact the aerodynamics of your motorcycle.  It's easy to access with a zipper extending around the entire circumference of the opening.  Molle straps and an elastic band on the lid allow for temporary storage for items you pick up along the way. The external carry handle allows for ease of use when taken off the bike.
