As promised herewith details and pics for my NT, hopefully it will be of help to others.

The saddlebags are by Kuryakyn (model) Edge 108 now discontinued and got them when on special for USA154.95 the pair reduced from $499. from Cruisercustomizing USA. They have to be mounted on the bike using EzyBrackets which arnt that cheap at USA$145. a pair. They simply slot on to posts that remain on bike. Also bags and brackets are lockable with keys. They are the best system to use for hardback saddlebags however not without its faults as indicated in my review

I also got wall brackets to suit to keep stored bags off the floor as I dont intend the bags to remain on bike permanantly. I also got a carry handle to transport the pair of bags.

Also a plug for items I have listed up for sale. Theres a sissy/rack bag that might be of interest to some http://www.ebay.com.au/sch/busa4u/m.html?_ipg=50&_sop=12&_rdc=1
