I love my seahorse 720 case as a topbox. Fits perfect on the CJ Designs rack, holds a ton of stuff, and has a backrest for the pillion. With the four strap bars I can put other gear on top. It's just a little wider than the grab handles back there, and doesn't look like an alien space ship following me. That they are $52 is just icing. No, my helmet doesnt fit in it. If I'm really worried about it I bring it in with me. I want a cable lock for helmet(s) and jacket(s) when that is the only option. Soft bags aren't so much to protect the bike as they are to keep you from running over your own leg offroad. Lot's a GS'rs with broken feet/ankles.
