Kawasaki Z900 2023

Kawasaki Z900 2023

The Kawasaki Z900 may not be up to scratch when it comes to modern, lean angle-dependent electronic features, but it's relatively cheap and you shouldn't underestimate the fan base of the good old inline four - the Z900 is one of the cheapest ways to own such a great engine with just under a litre of displacement in a sporty naked bike! The higher weight is noticeable, but not massively annoying, because the handling and stability are quite alright. In terms of "outdated" electronics, the most annoying thing is the missing shift assistant, which is not even available as an option. Overall, however, the Z900 is a great naked bike with a great price-performance ratio.

Light and natural handling with high stability

silky engine with full pull from low revs

high chassis transparency, great feedback

seating position with feel-good factor

absolutely fair price.

Relatively cumbersome operation of the menu

no slope-dependent assistance systems

high weight

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compromises comfort and the lack of a modern ride-by-wire system prevents the use of a blipper - making the ZX-6R look outdated compared to competitor models.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