I've had a gold one on my ZX-14 for a year and it's fine. The gold finish color is what I had a problem with so far. It's a bit light in color compared to most gold's you see on motorcycle parts.
Get a ZVX. It's a better chain and it's stronger. I'll bet it's lighter than a 3D too. The Z3D I put on my ZX-14 was a tad heavier than the old ZZZ when it was installed ten years ago. The ZVX is probably very similar to the discontinued ZZZ. I got a black ZVX for my busa. Still have not cut and weighed it. The gold finish on the ZVX looks very nice from what I have seen and both inner and outer plates are colored gold. I think the Black ZVX I have for the busa has silver or gold inner plates, it's not all black.
Here's the Z3D I have on my ZX-14. You might see how pale it looks compared to the sprocket. It's even a little more noticeable in real life.
