The Kawasaki Z900 2021 and the BMW F 800 R 2017 are both naked bikes that offer a thrilling riding experience. However, there are several key differences between the two models.

In terms of engine performance, the Kawasaki Z900 2021 comes out on top with its 125.4 HP engine, while the BMW F 800 R 2017 falls slightly behind with its 90 HP engine.

In terms of suspension, both bikes feature upside-down telescopic forks in the front and swing arm suspensions in the rear.

BMW F 800 R 2017

With a EURO4 engine, new riding modes, new instruments and new colours, the F 800 R starts the new season. It is recognisable at first glance only by the end cap on the stately stainless steel exhaust. It is one of those full-grown motorbikes that, despite its considerable sporting potential, was designed for the widest possible user group. Therefore, it is absolutely beginner-friendly (throttled), but can also inspire an experienced audience. Its character remains somewhat pragmatic, but the unmistakable, hollow sound of the inline two compensates for this.
