Pros and Cons in comparison

BMW F 900 R 2021

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

KTM 790 Duke 2018

KTM 790 Duke 2018

The KTM 790 Duke L is an absolutely sporty naked bike with a high fun factor. Whether a beginner rider can handle it depends very much on his or her personality and riding behaviour. There are certainly motorbikes better suited for learning, but sporty radius hunters will hardly be satisfied with anything else. The 790 Duke L is also rather unenthusiastic about everyday rides in the city. On the country road, however, it's a blast, even with only 48 hp. Simply a fun bike as it is written in the book.

Lively, high-revving engine with powerful acceleration

optimally tuned chassis for sporty riding

awesome sound even with series muffler

many electronic gimmicks and functions

extremely precise quickshifter that makes fast riding even easier

comfortable seating position

Rough handling at low revs

bitchy in city traffic

sometimes fiddly-looking switches on the handlebars

oil leak at the engine block on many 790 Dukes
