Yes indeed. It looks promising but I wouldn't like to pay more than 200 euro, say max 250 dollars. We'll see what it brings. I have cut off the handle bars and have strengthened the rear rack with some alu bars to the subframe und pillion seat. So now my Mosko Moto reckless soft luggage fits nicely. Not a bad solution but a decent solution would of course be better as long as it isn't too expensive!
SW-Motech makes a steel plate to take the place of the passenger seat. It may give more mounting points and save the hassle of removing the rail and rear moulded plastic area.
I could see how the grab rails might be an issue for the Mosko luggage or Giant Loop ones that are draped over the bike. Otherwise they look like they would serve as an adequate place to use straps to tie things down for a 30-60L dry bag.
