Pros and Cons in comparison

Kawasaki Z900 2023

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 In terms of "outdated" electronics, the most annoying thing is the missing shift assistant, which is not even available as an option.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.

The Ninja 650 firmly stamps its predecessor (Er-6f). The engine has mastered the Euro 4 hurdle well and serves up a very usable 68 hp, the chassis is simply great for this class, and the weight reduction of 18(!) kilos compared to the ER-6f justifies reverent nods.
