That's......awkward.
Why?
USA - Zee-Eks-14
UK - Zed-Eks-14
Not much difference to my mind, although it is called the ZZR1400 over here.
The double Z is awkward but it only ever occurs with Kawasaki motorcycles and a a certain collection of Texan Beards.
As for the rampant mutilations of the English language, you are not the only ones.
The Canucks, Aussies, Indians, South Africans, Jamaicans, Irish, and a great many others also mutilate and bastardise our language,.....
... but we can take it, we can handle it, because we have our stiff upper lip and a cup of tea.
Oh Bryn,... it's Zulu by the way.
