Kawasaki Z900 2021

Kawasaki Z900 2021

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 In terms of "outdated" electronics, the most annoying thing is the missing shift assistant, which is not even available as an option.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

KTM 890 Duke R 2021

KTM 890 Duke R 2021

The KTM 890 Duke R is the sportiest evolutionary stage of the 890 Duke. More power, firmer chassis, sharper brakes - these ingredients, together with the already low vehicle weight, make it a real precision machine. A fast and cool bike for riding fun fetishists, ambitious home track heaters and, last but not least, a real recommendation for trackday visitors. However, the sporty positioning of the upper body and the somewhat more acute knee angle come at the expense of comfort. Last but not least, the adjustable suspension in the basic setup is really crisply tuned. If you want to enjoy the powerful 890 engine and the high-quality electronics a little more comfortably, you can still go for the basic model with a clear conscience.

powerful and rev-happy engine

finely controllable response

good (optional) quickshifter

sporty seating position ensures great front-wheel feel

high-quality adjustable suspension

powerful Brembo brakes

low vehicle weight

extensive (partly optional) electronics

Sitting position more demanding than on the basic model

tight basic set-up not to everyone's taste
