You can have them for £200, they were £472 for the pair, though it looks like you can get them for £450 now from kawasaki original parts

Lock Cylinder Set (2 locks) +£37.36
Pannier Covers (15T/17L Candy Burnt Orange) +£103.45
Deco Stripe Kit (15T/17L Candy Burnt Orange) +£29.74
Pannier Covers (25Y Pearl Stardust White) +£103.45
Deco Stripe Kit (25Y Pearl Stardust White) +£29.74
Pannier Covers (660 Metallic Spark Black) +£103.45
Deco Stripe Kit (660 Metallic Spark Black) +£29.74
Pannier Fitting Kit (Kit) +£132.91
Fitting kit seems a bit of a rip off as I think it is just the two rubber bungs they slide onto and then a small sticker that sits inside the grab handle.
I will try to get some pics at lunch time of the damaged one.
