Pros and Cons in comparison

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

BMW F 900 R 2021

The BMW F 900 R is a full-grown motorbike. 895 cc, 105 hp and 92 Nm smell of versatility. The F 900 R fulfils this promise completely. The motorbike, including electronics and components, does a great job in every situation. But of all things, the heart of the bike, the engine and transmission unit, does not shine in premium gloss.

Great cockpit and functional connectivity

Extensive electronics can be operated logically

Very accessible but still very casual handling

Motorcycle rides bland and reserved but also wild and sporty when needed

Pleasant seating position

Wide choice of equipment and configuration options

Low and high seat options available

Suspension allows wide range of use - comfortable but also direct and precise.

Gearstick a little stiff - with and without quickshifter

Engine runs a little rough and exudes little elegance at the top

Poor splash guard at the rear
