Pros and Cons in comparison

KTM 390 Duke 2023

KTM 390 Duke 2023

The KTM 390 Duke is a bike that can polarise. Its strengths lie in its extensive electronic equipment, agile handling and ability to serve as a fun bike for young riders. However, the firm riding position and inconsistent engine tuning could be annoying for experienced riders. Yet the KTM 390 Duke offers plenty of riding pleasure, especially in urban environments and on sporty rides.

Suzuki DR-Z4S 2025

Suzuki DR-Z4S 2025

The Suzuki DR-Z4S is an all-round successful comeback - not a shallow retro rehash, but a consistently modernised further development of a popular and proven concept. It remains true to its line: robust, easy to use, versatile and yet capable of many things. It is a bike for a small niche of riders, between hard enduro riders and adventure bike riders. For this niche, however, it fills an important gap as a true dual sport bike and hardly allows itself any weaknesses. The most critical points are the remaining 5-speed transmission and the high price. Whether these points discourage a purchase or whether the DR-Z4S is still worthwhile as a legend and versatile vehicle remains a matter of taste.

Great, smooth yet powerful engine that makes off-road riding easy

Beautifully responsive KYB suspension with a wide adjustment range

Good-natured yet agile handling

Excellent gravel mode of the traction control

Intuitive operation of the electronics

Active ergonomics

Good country road and long-distance qualities

Nicely controllable brakes

Fills a gap in the motorbike segment

Long gear ratio as limit for tough off-road use

Fork preload not adjustable

Handlebars a little low for tall riders around 1.90 metres

Standard tyres as a limit on loose off-road terrain

High price for an A2 bike
