Pros and Cons in comparison

Kawasaki Ninja ZX-6R 2020

The Kawasaki Ninja ZX-6R is a perfectly sized supersport motorbike. With its 130 hp, sporty but controlled riding is possible. The shorter gearing and the 36cc extra displacement ensure that you can be a bit lazier on the road. A worthy flag-waver for the 600cc supersport segment.

Great engine with a great mix of revving and torque

supersport pleasure with lively handling - but still no ascetic feeling in the saddle

well responsive fork and decent, adjustable chassis.

Some details could do with more finesse - number plate holder and indicators!

The overall silhouette is not sporty enough. The sporty bike could do with more aggressiveness.

Kawasaki Z900 2025

The new Z900 masters the balancing act between modernisation and proven virtues remarkably well. The 6-axle IMU, the precise quickshifter and the new electronics package make it technically absolutely up-to-date, while the characterful four-cylinder engine loses none of its fascination despite Euro 5+. The harmonious setup of all components is particularly impressive: whether suspension, engine or ergonomics - the overall package is just right.

Harmonious engine with impressive acceleration in the mid-range

very well functioning quickshifter with precise responsiveness

mature riding performance with a good compromise between stability and nimble handling

sensitive 6-axle IMU with harmonious control

superbly tuned seating position

excellent engine reponsiveness

confident cornering behaviour with transparent feedback from the front

harmonious electronics that do not restrict riding pleasure

smooth transmission with perfectly tuned ratios

first-class stop-and-go behaviour in city traffic

intuitive bike for beginners and experienced riders

slim waist despite four-cylinder layout
