Pros and Cons in comparison

Kawasaki Z900 2023

The Kawasaki Z900 may not be up to scratch when it comes to modern, lean angle-dependent electronic features, but it's relatively cheap and you shouldn't underestimate the fan base of the good old inline four - the Z900 is one of the cheapest ways to own such a great engine with just under a litre of displacement in a sporty naked bike! The higher weight is noticeable, but not massively annoying, because the handling and stability are quite alright. In terms of "outdated" electronics, the most annoying thing is the missing shift assistant, which is not even available as an option. Overall, however, the Z900 is a great naked bike with a great price-performance ratio.

Light and natural handling with high stability

silky engine with full pull from low revs

high chassis transparency, great feedback

seating position with feel-good factor

absolutely fair price.

Relatively cumbersome operation of the menu

no slope-dependent assistance systems

high weight

Kawasaki Ninja ZX-4RR 2024

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
