Pros and Cons in comparison

Kawasaki Ninja ZX-4RR 40th Anniversary Edition 2024

The Kawasaki Ninja ZX-4RR proves to be an impressive sporty bike that will particularly delight lovers of high-revving four-cylinder engines. With its distinctive sound and excellent braking performance, it offers a riding experience that is convincing both on the road and on the race track. The sporty ergonomics and precise handling make it a good choice for beginners and smaller riders looking for a super sports bike suitable for everyday use. However, the engine requires high revs, which can be tiring on longer journeys, and the display looks a little outdated compared to modern standards. Overall, the ZX-4RR offers a lot of riding pleasure and is a welcome addition to the small-volume supersports segment.

Impressive four-cylinder sound

Well-functioning quickshifter

Sporty, stable suspension with good handling Ergonomic, sporty but comfortable riding position

Good modulation and sufficient braking power

Suitability for everyday use despite sporty orientation

Simple operation of the controls

High revs required for optimum power

Slow setting of riding modes

High noise levels due to high engine speeds

Suzuki DR-Z4SM 2025

The eye-catching graphics from Suzuki Austria suit this bike well. For me, however, the joy of life doesn’t come from the graphics, but from the ride itself. The DR-Z4SM succeeds in combining a familiar, solid feel with genuine playfulness. On the one hand, it offers a predictable riding experience; on the other, it has enough supermoto character to ensure the fun doesn’t stop straight away, even as your experience grows. Those looking primarily for maximum power will continue to look towards more powerful machines. I’d take this Suzuki for a test ride because of its seamless interplay of features: precise handling, smooth gear changes and an engine that remains easy to read whether you’re opening or closing the throttle. My brief test doesn’t provide a long-term assessment, but it does offer a clear personal verdict. I felt comfortable in the saddle and would have liked to have carried on riding.

An instantly familiar, accessible driving experience

butter-smooth, harmonious gear changes

a predictable engine under load and when coasting

precise handling without feeling twitchy

Less power in reserve than more powerful supermotos
