So, using some left over money I had been saving up I purchased a new top box that fits on my existing rear rack. It is a Givi E470 Mono-Key top box. 47 liter capacity. I can put all kinds of stuff in there, but it will be most useful for commuting and putting my laptop bag in and allowing it to be locked if I want to do something right after work. Now, I don’t have to go home to drop off the laptop before heading out. Besides, I can carry my rain gear in case I am not wearing my Klim stuff for some reason and my air compressor and tire repair kit as well. And, if I dont want to have it on, it comes off in a snap with the turn of the key.
