Kawasaki Z900 2021

In terms of price-performance, the Kawasaki Z900 is hard to beat at the moment. With the perfectly tuned engine, the high-quality chassis components and the electronics added for 2020, this naked bike offers everything that sporty riders will be looking for. There is really nothing to complain about, except for the lack of a quickshifter option.

You can always argue about the looks and the lack of a trellis frame, but the current Monster is anything but ugly. Basically, it would be a great everyday naked bike with pleasant ergonomics and a braking system that does not surprise even the inexperienced. The rather soft chassis can also be considered an acceptable compromise, but for a Ducati it is rather surprising that at least the front fork was not tuned a little tighter. Unfortunately, the charismatic engine bucks strongly at low revs and thus only shows its wonderful V2 character on the country road. All in all, however, this reflects the overall image of the Monster very well: a typical Ducati that is also good for everyday riding in terms of chassis and brakes.
