Most bike names are used worldwide (either in english or not): Hayabusa, Fazer, FireBlade, Tuono, Ninja, Hurricane, Katana, Speed Tripe, Daytona, Raptor, Monster... The list goes on an on.
Sometimes the name is dropped in some countries due to having already been registered by other company, or due to being too aggressive for the company lawyers.
Like it or not, english is now Earth "Lingua Franca" (universal language), and japanese and italian monickers are fashionable.
In spanish we have the advantage that the pronunciation of "Hayabusa" is quite close to the japanese, while in english you need to be told how to pronounce it.
