Pros and Cons in comparison

Kawasaki Ninja ZX-6R 2025

The 2026 Kawasaki Ninja ZX-6R is a bike that almost goes against the spirit of the times, which is precisely why it is so appealing. While many manufacturers have long since abandoned the classic supersport class, Kawasaki is sticking to the idea of a lightweight, high-revving, precise and uncompromising sports motorbike. The 636cc engine runs wonderfully smoothly, offers real supersport emotion at high rpms and has more usability than classic 600s thanks to slightly more displacement. The suspension is precise, confidence-inspiring and works well both on the road and on the race track. The brakes are firm and powerful. The electronics are not the most modern, but are sufficient and well setup in practice.

silky smooth and revvy 636 cc in-line four-cylinder engine strong running culture and very good modulation

precise, confidence-inspiring suspension

powerful and stable brake system

very good transmission with cleanly functioning quickshifter

more modern appearance with TFT, LED lights and smartphone connectivity

more suitable for everyday use than classic 600cc supersports bikes

Tight ergonomics, especially for taller riders Quickshifter only for upshifting

No Ride-by-Wire and no blipper

Rear wheel ABS cannot be deactivated separately

Wind protection rather tight as standard

Electronics not at the latest supersport level

Suzuki GSX-S1000S Katana 2019

The Suzuki GSX-S1000S Katana is based on the naked GSX-S1000 and therefore impresses with all the quality and inner values of a typical Japanese machine. The Katana also has what it takes to become a visual classics, as it is the first to take up the style of the 1980s. The riding position is surprisingly comfortable and the height of the handlebars allows for comfortable control. With its low front fairing, it may not be a true touring machine, but it can certainly pass as a crossover bike that combines retro, naked and touring perfectly.

Powerful and confident in-line four-cylinder engine

absolutely unique look

comfortable seating position

easy handling

five-way adjustable traction control

good braking system

high-quality quickshifter

firm but travel-ready suspension

Few electronic features

relatively high price compared to the basic GSX-S1000
