The GS also impressed us with its versatility during the test in November 2021. We rode the bike on a wide variety of terrain and were once again very satisfied. The motorbike convinces in every situation with its easy handling and practicality. On the other hand, it can also be ridden delightfully irrationally.

Great ride comfort and great ergonomics

Powerful engine

Great connectivity app

Easy-to-read display

Confident feel in the saddle

Practical riding aids

Versatile chassis accommodates every route

Easy to ride

Rough overall appearance

gearshifts at low revs somewhat clumsy

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
