I like the panniers on my K1600GT for most trips. But they make the bike very wide. Many times I don't need the capacity, but still like something lockable. BMW used to have "City Cases" or city case replacement lids for their older style panniers. The width and capacity is reduced, but for a trip to the office or work site, it is perfect. Does anyone know of anything available out there? A lid that that I can swap with the normal lids?
