I keep a E52 topbox on my '01 most of the time for commuting, as others have said its a great secure, dry storage for cold/wet gear, laptops, etc. I comute over 200 miles per day and wouldnt be with out it. The E52 is a little large and I did manage to overload it when it was used on my Trophy to the point of breaking a weld on the tail frame, did you know that an E52 will hold a case and a half of beer and two bags of ice (kids dont try that at home, Im a professional). Ive learned my lesson and have kept the loads within reason on the sprint and todate, no problems. I installed an SW Motech rack

Kory, I like to think of the topbox on my ST as a tribute to the Air Force, I refer to it as the "AWAC" look.
