Another foible to be aware of is the illusion of capacity-while hard bags may appear huge on the outside, some are oddly shaped to better match your bike's lines, leaving you with nooks and crannies on the inside that aren't particularly useful. Unlike soft bags, they won't expand as you keep cramming stuff in. Plus, mounting brackets can position the bags pretty far out, adding significant width to your motor-cycle, so you might want to familiarize yourself with the extra girth before setting out. Be sure to measure pipe and strut clearances as well. Even with the bags off, you're often left with brackets that might not exactly score fashion points at your next cruiser function.
