Heres Kawasaki USA's conversation about what colors to bring into the USA. I can't prove this, but I'm pretty sure it went down this way.
Let's import the black color. What? I have to import the se as well? We will take those in black, but let's be innovative and choose metallic black. What do you mean the se is not available in black? Well, ok then. We will order the black and green.
Under no circumstances shall anyone check the box next to the blue bike, do you understand me? If anyone orders a blue bike, you'll be emptying trash bins, at Suzuki, before your shift is over.
Kawasaki USA didn't even import any of the anniversary red/black bikes. I think this blue is a great color, but it's a bridge too far for the USA.
