I have an NTX on order, the U.S. bikes should be arriving 2nd week of May.
I looked at the Trax top case but ended up buying a small Givi topbox with backrest pad just so the wife would have something for two-up riding. Other than that the topbox will stay at home.
My question is mostly about how stiff that support apparatus feels to those of you who have mounted a top box or case. The weight limit is not much (12.5lbs?) which is typical for topboxes... but does it feel pretty stout and secure?
Enough that a pillion can use the backrest without feeling like they're going to snap off a little bracket?
