Pros and Cons in comparison

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

Suzuki's evolution of the GSX-S1000 is a complete success. Although it is an old acquaintance in terms of its basic design, with the 2021 update to Euro5, as well as numerous revisions, the Japanese have created a wonderfully rounded package in the power naked segment. The engine, throttle response and quickshifter work flawlessly, and the suspension and brake components are tuned for sporty comfort. A bike with which you don't have to hide - unless someone wants to examine the display...
