Pros and Cons in comparison

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 Z900 2018

Kawasaki Z900 2018

In the hotly contested naked bike segment, the Z900 plays right at the front. Above all, its engine is absolutely terrific, runs incredibly silky and offers rich power in all rev regions - as befits a Japanese four-cylinder. Its sporty, aggressive appearance matches this. It does without electronic bells and whistles, but still conveys a lot of confidence when chasing corners, braking and accelerating out of them. The low seat is especially beneficial for smaller riders, but taller riders might miss a flatter knee angle on long distances. The low weight and compactness make the Z900 particularly agile and easy to handle. A sporting cannon that is also extremely appealing in terms of price
