i didn't click on the hyperlink, so not sure if you're referring to the medium-size or large-size, but i bought three of the large boxes for my 2nd fj and modded the already-installed krauser rack to fit the jcw's, to have a givi-wannabe 3-case setup. as these are not givi, and are only advertised as topboxes, and as i had two of them mounted as side cases, i was never at ease with the two side cases. the original plates sent were a hard plastic, and the one for my top box broke. apparently i was not the only one, as within about 6 months they voluntarily sent out replacement steel plates. as someone else mentioned, the screw securing the locking plates soon came loose on one of the side cases, and i had to epoxy it in place, with little room for extra epoxyspooge.
if i were to do it again, except for the fjr, i'd consider it. if your fjr is running smooth, you don't abuse it, and you keep an eye on the box (checking screws, mounting hardware, etc.), you will get your money's worth out of it. in the time you have it, save up your money for the givi, or shad, or whatever else well-made boxes are that people are using for the fjr, so when the jcw box dies, which it will, you'll be ready for the good stuff.
the question was brought up as to the size of the jcw boxes---they're about the same interior size of the fjr's, again i'm referring to the large jcw boxes. however, they seem to hold more, because their shape is rounder, not so angular and boxy as the fjr.
