I have a set of large Tusk Aluminum side cases (leftovers from my VStrom days), that are significantly more spacious/waterproof/secure than the OEM cases on my ST1100, and have been musing on how I might fabricate some side racks to mount these on my 2001 ST1100. I would want to use them only for my longer summer expeditions, so they should be easily removable, so I can use the oem cases the rest of the year. Has anyone done this? i.e. fabricated racks to use 3rd party pannier cases on an ST? Any tips/pics/pointers would be muchly appreciated.
