KM is completely right. Even if it seems badly grooved, it's the thickness that matters. You can install new pads on grooved discs, and they will bed in quickly to fit the grooves. BUT, I understand your problem. Here we have emissions tests, and no matter how good the vehicle is running, or how safe it is, you can't get it registered until you pass one of those communist type things.
Unfortunately, I don't have a solution. I have no way to cross-reference Kawasaki part numbers to see if those discs are used on any other bikes. Like many carbs, I'd say there is a good possibility they are, I just don't know what. You are lucky on the price, they are $270 each here. The disc on my Yamaha XT225, which is common in the UK, where it is called the "Serow" is $35. It's a little smaller, but not nearly enough to account for that kind of difference in price.
I am a motorcyclist, NOT a biker.
