Hi! I don't know if you are short on bucks, but I just bought Gobi Hepco and Becker hard bags (37 liters) with a frame. The bags are HUGE, sit high on the bike and clear the mufflers by several inches. They remove easily, lock, and are waterproof. They mount easily but...the wires they send in the set to relocate the rear directionals are too short. So far my only problem is mounting - I am short and throwing my leg up over the whole mess is pretty daunting. Even my 6 foot tall husband has trouble. I think practice will get me there, eventually. The bags are awesome, add a little weight to the bike but I hardly notice it. For the added protection of gear (laptops and cameras) and because the mounting was made specifically for the 500 I thought it a deal not to have to jurry rig anything. The mount was expensive but when I got it, I could see why. It is pretty tough and has extra pieces that add support for the bags - such as a part that fits neatly behind the wheel and connects both bag supports together. Also there is a support on top that can be used for a top case. These are heavy duty bags made for hard travel. My husband and I plan to take a cross country trip this coming summer, so hard bags were a must investment. It was just a matter of which ones. Sometimes spending a little more money is worth it when everything fits so neatly. Best of luck.
