Kawasaki Ninja ZX-6R 2025

Kawasaki Ninja ZX-6R 2025

The Kawasaki Ninja ZX-6R impresses with a powerful 636 cubic centimetres engine and dynamic handling, making it a thoroughly potent and sportily tuned machine. The well-functioning quickshifter and clear display contribute to a positive riding experience. However, the aggressive riding position significantly compromises comfort and the lack of a modern ride-by-wire system prevents the use of a blipper - making the ZX-6R look outdated compared to competitor models. Overall, it is an excellent choice for riders with sporting ambitions, but offers room for improvement in terms of comfort and modern features.

Powerful 636cc engine with plenty of grunt and power

well-functioning quickshifter at high rpm

good handling and pleasant ride feel

clear and easy-to-read display

sporty suspension

reliable brakes

Missing Ride-by-Wire system - therefore no blipper

aggressive riding position with acute knee angle and handlebar ends turned inwards

lack of comfort for longer rides

somewhat spartan display compared to the competition
