The 96-03 B6's all use the same rotors.

You can check the parts fiche at Ron Ayers and see if other Suzukis use the same rotors. I did a quick check of a couple different years of 600 & 750 Katanas and they had different P/N's. That doesn't necessarily mean they won't work, something as simple as a different color paint on the center carrier would give them a different part number.
You might pose this question to a m/c salvage yard. They may know the answer. I know in the car world, these yards have a set of books called "The Holland Interchange Manual" that will tell them what stuff is the same across various makes, models & years. It wouldn't surprise me if there isn't a similar publication for bikes. Since brakes are generally outsourced to other vendors, the same rotor may be found on a non-Suzuki, too.
