Kawasaki Ninja ZX-4RR 2025

Kawasaki Ninja ZX-4RR 2025

The mere fact that the Kawa Ninja ZX-4RR with its high-revving Inline four-cylinder engine in bonsai format has no real competition makes it absolutely unique. The engine is also the absolute flagship, with a rev limit at 16,000 touring you'll be addicted to wind out a gear! The suspension, brakes and electronics are of a high height, but what is more surprising is that, despite all the sportiness, the bike is still very suitable for everyday use - the seating position is not as radical as on other supersports bikes.

Fun in-line four-cylinder

KTM 990 RC R 2026

KTM 990 RC R 2026

The KTM 990 RC R is a supersports bike that never denies its origins, but can do much more in everyday use than you might think at first glance. On the race track, it impresses with high stability, plenty of feedback, a powerful, easily controllable engine and ergonomics that also support ambitious riding. In everyday use, it scores points above all with its excellent touch display, integrated navigation and surprisingly good motorway qualities. At the same time, however, it demands a willingness to compromise from its rider: heat in city traffic, the sporty seating position and brakes that require a little more force make it clear that comfort has never been the top priority here. But this is precisely where its appeal lies: the 990 RC R is not a sensible everyday motorbike, but an emotional supersports bike that makes even ordinary journeys special.
