The Kawasaki Ninja ZX-25R is a crazy machine. Maybe not quite as crazy as the small-displacement screamers from the heyday of sport bike design, but still crazy enough in a world of tightening regulations and budget-focused OEMs.
Of course, we know that the Kawasaki Ninja ZX-25R was made for markets where the Kawasaki Ninja 400 was too expensive to own, primarily because of taxes, insurance, and licensing structures.
This is also part of the reason why the 50hp 250cc machine doesn’t come to the USA or Europe, but instead finds a home in the Asian markets.
Now, we get word that rumors have begun about an encore to Kawasaki’s craziness – a four-cylinder 400cc machine that could be called the Kawasaki Ninja ZX-4R.
