Kawasaki Ninja ZX-4RR 2025

Kawasaki Ninja ZX-4RR 2025

The mere fact that the Kawa Ninja ZX-4RR with its high-revving Inline four-cylinder engine in bonsai format has no real competition makes it absolutely unique. The engine is also the absolute flagship, with a rev limit at 16,000 touring you'll be addicted to wind out a gear! The suspension, brakes and electronics are of a high height, but what is more surprising is that, despite all the sportiness, the bike is still very suitable for everyday use - the seating position is not as radical as on other supersports bikes.

Fun in-line four-cylinder

precise quickshifter with blipper

balanced handling

sporty and pleasant ergonomics

comprehensive electronics package

Engine needs to be kept happy

looks confusing with other Kawasakis

Kawasaki Ninja 400 2018

In summary, the Ninja 400 could be described as the perfect entry into the supersport world. You can't get more power with A2, the looks suggest much more power, the vehicle is playful to ride, is forgiving in every respect and still allows a really sporty riding style. Those who had legitimate concerns about the lack of power on the various 250 cubic machines now have no more excuses. Ninja 400, it's good to have you!
