I think I need to clarify ... I attached the 2 BMW GS1200 pockets/bags (good for small tools and locks) under the sides of the GIVI rack/base which my GIVI top box was connected to, and then clipped them to the rear GIVI pocket/bag which sat under the GIVI rack, which the top box was connected to.
I would imagine this set top would work for any rack combo.
Thanks
