The Journey side cases will accept a full-face helmet with room to spare. You
might even be able to get two in there if you tried hard enough.
I've been very happy with the bags. They hold a lot are are watertight. My wife has no complaints about foot room, although she is very small (fwiw, 4'11", size 3 shoe).
Some folks have had trouble with the latches breaking. While Buell is replacing broken latches free of charge, your best best is to use one hand to hold the bag fully closed, and the other to close the latch. Don't use the latch to pull the bag closed, and stop if you feel any resistance.
