I have the old Rattlebars chrome on one bike, and newer xf6 Customs (Darryl's) stainless bar grille on the other, and they are really unique, nice bling (and very well made; they are individually brazed in, one rod at a time). They are different from any other bolt on chrome. (They also do not block any necessary air to the radiator; some of those flat stock covers with cut-out designs in them block an awful lot of air).
Word to the wise, if you will reuse your OE rattletrap grill underneath the bar grill, the mount screws are longer than if you don't use it. I do not use the OE grills underneath on either bike, (never had a rock or anything other than bugs to be swept out with a soft brush in tens of thousands of miles), and I got the wrong longer screws with my 2d grill, and if I was not paying close attention, I could have holed the radiator with just the 1/4" longer screws.
If you will reuse the OE grill, it needs cleaned, wire wheeled, and hit with a rattlecan (I recommend flat paint, you are not trying to compete with the bar grille). Mine were in bad shape. They could have been brought back, but I didn't want them in there anyway.
BTW, I don't know if they are sold anymore, but there used to be aftermarket chrome (or chrome colored) grills exactly like the OE black ones for sale, for much cheaper than the bar grilles.
Also beware, the old (I think now discontinued) Show Chrome braided stainless hose cover was notorious for leaking coolant. I cannot remember what the problem was, it may have only been crappy clamps, but that part gave a lot of people trouble (if it even still available). See below:

While not as fancy as nice braided stainless, you can still get the Interstate radiator hose (slinky) cover as Honda OE parts. They sit inside the clamps and never leak, and look much better than a bare hose on tourers/stds. Part no 19 in this '99 interstate fish ($27.65 on Partzilla).

Hard to find good close up pics of one on interstates.
