My 929 arrived Tuesday, and this evening I had a chance to take it out for a good, long look-see. The short story:
I've seen the real GIVI E460 in the flesh. This box isn't it by a long shot, but I knew that going in. The box material feels like ABS, and the fit of the parts is actually pretty decent. The trim isn't much to write home about, but if you're just after a place to stash your helmet when stopped, it'll probably do just fine. It's still leaps and bounds better than a milk crate and doesn't seem to be a complete disaster, either.
I've decided to return mine, though, because the mounting hardware won't adapt nicely to the ST. The plate snaps onto the bottom of the box very securely, but it has a triangular punt in it, probably for structural rigidity. Unfortunately, it's right in the spot where I'd need to add holes for it to fit the ST as I wanted. I did like the liner they sent with it and will probably buy a set of their saddlebag liners.
So, Paul at GIVI, if you're reading this, your company will probably be getting some of my money, either directly in an E460N or indirectly in the form of a Hondaline box. You guys do make good stuff, I don't think there's any debating that. Once in awhile, the knockoffs get it right, and somebody has to guinea pig them. I probably wouldn't have tried it out if CB didn't have such a good return policy.
