Ok so good news..sort of.
The OEM silver pannier top box that comes with the SE package sits on a plate, which is bolted to the bike. This plate will take the older honda top box I mentioned earlier. The locking mech on the new CT silver box is identical to my older Honda box..it just looks abit neater. So those of you who have the CT luggage, can in theory put a different top box (Must be honda though) on the back. The problem is now..can I buy that plate seperately, and if so, how much will it cost...knowing honda..a fortune...i'll let you know
