Kawasaki Z 400 2023

Kawasaki Z 400 2023

A cool and sensible entry into the A2 class. The Kawasaki Z400 scores points all along the line with its instinctive handling and the in-line two-cylinder, which convinces with good response and sufficient power. You can't go wrong with this naked bike and you can overlook the fact that the levers are not adjustable - after all, costs have to be saved somewhere.

Aprilia RS 660 2021

Aprilia RS 660 2021

In 2021, the Aprilia RS 660 can be seen as the last true 600cc supersport, because with its sporty seating position and high-quality chassis components, it hits the sweet spot between suitability for everyday use and trackday potential. Thanks to the comprehensive electronics package, nothing is left to be desired on the road or on the track - and you can't complain about the powerful two-cylinder anyway. A great package for all those for whom 200+ hp superbikes are too much for everyday use.
