Pros and Cons in comparison
Pros and Cons in comparison
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
