A neighbor's son had a Yamaha XS1100 "Midnight Special Edition" gold-trimmed bike he wanted to get-rid-of. It didn't run, and was like that for years. The bike was a couple blocks from a brackish water connection to the ocean, so the salt air had done a number on the black & gold finish. The bike had a lot of that white oxidation that aluminum gets from salt, so it definitely wasn't "clean," and as a non-operable bike, it was 'way-overpriced. I would've taken it for $500, but for three-times that, no-way!
The John Player Special Nortons always looked pretty-good, I thought.
A Yamaha VMax with a tasteful amount of gold trim could look neat, but it's a delicate balance between 'neat' and garish. I would say, "less is more." For wheels, a gold rim and black centers would look better to-me than an all-gold wheel. Contrast that with some 1/4" pinstriping boxing-out the body tins' lines, maybe a few smaller brackets also done in gold, maybe the calipers, and you would have a tasteful combination.
