Pros and Cons in comparison

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compromises comfort and the lack of a modern ride-by-wire system prevents the use of a blipper - making the ZX-6R look outdated compared to competitor models.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

Kawasaki Z900 2017

An incredibly well-designed motorbike. A lot of test work and attention to detail went into it. It has exactly the right power, exactly the right chassis and exactly the right look. An all-round successful naked bike that will make you happy for a long time. If you like, you can ride it simply and faithfully, but if you want, you can also ride it really fast and it wheels like hell. Great!

Ingenious nakedbike chassis

superb looks

engine responds super fine, revs up willingly and has a perfectly dimensioned torque

optimum intersection of performance, price and practical use

Knee angle very narrow for tall people (order another seat!)
