Pros and Cons in comparison

Kawasaki Ninja ZX-6R 2024

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.
