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 In terms of "outdated" electronics, the most annoying thing is the missing shift assistant, which is not even available as an option.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 RC 390 2022

KTM RC 390 2022

The KTM RC 390 presents itself as a sporty and dynamic bike that is particularly suitable for riders looking for an agile and manoeuvrable machine. Its fully adjustable suspension and low weight ensure precise and easy handling, while the comprehensive electronics package, including the innovative supermoto ABS, offers additional safety and riding pleasure. The engine, on the other hand, shows weaknesses in power delivery, especially at low revs, which is not what you would expect from a single-cylinder engine. The aggressive riding position is a double-edged sword: it enables a sporty riding experience, but can be uncomfortable for longer rides.
