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

Suzuki GSX-8S 2023

Suzuki GSX-8S 2023

For years, Suzuki was the brand that offered nice bikes at a good price/performance ratio. With the Suzuki GSX-8S, the brand is much more self-confident. It presents itself as high-quality, mature and places itself at the top of a hard-fought class. The unspectacular performance data and the relatively high weight tarnish the picture only briefly. During the test rides, the Suzuki was completely convincing. A really good motorbike.
