The 2019 Kawasaki ZX6R and the 2017-2019 Kawasaki Z900 are both powerful motorcycles belonging to the renowned Japanese manufacturer. There are several significant differences between these two bikes, starting right from the basic characteristics.

The 2019 Kawasaki ZX6R is a sports bike widely popular among sport enthusiasts for its top-notch race-inspired technology. It is equipped with a 636cc liquid-cooled engine, six-speed transmission, and adjustable suspension, which provides superior handling, excellent balance, and precise control at high speeds. This bike is designed for riders seeking to push their limits and experience the ultimate thrill of speed.

On the other hand, the Kawasaki Z900 is classified as a naked sportbike, which arrives with a 948cc inline-four engine that delivers a perfect blend of power and performance. It also features a six-speed transmission and fully adjustable suspension, but the main difference is its compact, lightweight design, enhancing its agility and making it an ideal choice for everyday commuting and long-distance touring.

The targeted audiences for both of these bikes would vary widely because of their different characteristics. The ZX6R targets experienced riders, professionals, and those who crave high-speed thrills on the tracks, whereas the Z900 is aimed at riders of all levels who seek adrenaline-fueled fun in everyday riding.

Compared to the Z900, the Kawasaki ZX6R shines with its aggressive seating position and ergonomic features, putting the rider in perfect control to achieve their best performance. The ZX6R's aerodynamic design, comfortable seat, and advanced features, such as racing ABS brakes, provide superior safety while pushing your limits to the edge. However, the Z900 features a higher displacement engine, making it more powerful, lighter, and efficient even at low speeds. Its comfortable ergonomics, responsive handling, and smooth ride give it an edge over ZX6R as a daily ride.

As for the areas where they let down, both of these bikes come with some trade-offs. The Kawasaki ZX6R's extreme performance comes at the cost of comfort, which makes it challenging to ride for an extended period, making it less suitable for touring. On the other hand, Z900's excellent handling and comfortable ergonomics compromise its aerodynamic design, reducing rider protection against high-speed winds and weather.

In conclusion, both the 2019 Kawasaki ZX6R and the 2017-2019 Kawasaki Z900 are great options for riders who seek high performance and thrilling
