In terms of strengths, the Kawasaki Z900 2018 is praised for its powerful and silky engine, great sound, sharp and sporty look, low seating position, and easy handling and manoeuvrability. On the other hand, the Suzuki GSX-S1000 2021 is praised for its powerful engine, smooth quickshifter, sporty handling, comfortable seating position, and aggressive look.

However, the Kawasaki Z900 2018 does have a couple of weaknesses. It lacks traction control, which can be a disadvantage in certain riding conditions. Additionally, the knee angle may be strenuous for tall riders during long rides.

The Suzuki GSX-S1000 2021 has one notable weakness, which is that the display can be difficult to read, potentially causing inconvenience and reduced visibility while riding.

In summary, the Suzuki GSX-S1000 2021 offers more power, advanced rider assistance systems, and better adjustability in terms of suspension compared to the Kawasaki Z900 2018. However, the Kawasaki has its own strengths, such as a powerful and smooth engine, great sound, and easy handling. Ultimately, the choice between the two models will depend on individual preferences and priorities.
