I plan to install Al Jesse panniers on an R1200GSw (2013) and will also mount a custom-built platform on the pillion/rear rack area for transporting my trusty K-9. In order to move forward with construction on the K-9 platform, I need the distance measure between the vertical inboard side panels of a pair of Jesse panniers (in CM or inches) to be sure that the lids on the panniers, when raised, will clear the outer rails of the K-9 rack situated above. The panniers are back-ordered and delivery is not expected for 7-10 weeks, so I cannot take the measures directly until they arrive. If possible, I would like the K-9 rack build to proceed concurrently, rather than waiting until the panniers arrive to obtain this clearance measure. If anyone has a 2013 or later R1200GS, R1200GSA, R1250GS, or GSA and the Jesse Challenger panniers mounted on it and can tell me the approximate distance between the inner walls of those panniers, I would be most obliged! Cheers to all. Eric
