Kawasaki Z900 2025

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

Great 5 inch display but the possibilities are not perfectly utilised with the Rideology app

licence plate holder seems a little carelessly integrated into the design

fuel consumption in practice significantly higher than factory specification (6.0-6.5l instead of 4.8l)

suspension of the basic version a little stiff on poor asphalt

promised app functions not yet available at the time of testing

Despite its sportiness, Ducati's redesigned and equipped Supersport 950 /S offers a good degree of suitability for everyday use and sufficient power for the country road or occasional trackdays. If you want to remedy the last remaining shortcoming, the throttle response in the lower rev range, which is characterised by load changes, you could consider changing the secondary gear ratio from 15/43 to 14/43. The one-tooth smaller drive pinion costs only a few euros, improves throttle response at low revs and also keeps handlebar and mirror vibrations within acceptable limits.
