The Kawasaki Z900 2017 and the Kawasaki Z1000 R 2017 are both naked bikes with similar engine types, fuel systems, and cooling systems. However, there are several differences between the two models.

In terms of engine power, the Z1000 R has a higher horsepower rating of 142 HP compared to the Z900's 125.4 HP. The Z1000 R also has a higher torque rating of 111 Nm compared to the Z900's 98.6 Nm. This means that the Z1000 R will have more power and acceleration capabilities compared to the Z900.

Both bikes have four cylinders and a liquid cooling system, ensuring efficient engine performance. The Z900 has a displacement of 948 ccm, while the Z1000 R has a displacement of 1043 ccm, indicating that the Z1000 R has a slightly larger engine.

In terms of suspension, both bikes have upside-down telescopic forks at the front and swing arm suspension at the rear.

Both bikes have a double cradle frame, but the Z900 has a steel frame while the Z1000 R has an aluminum frame. The aluminum frame on the Z1000 R is likely to be lighter and more rigid, providing better handling and stability.

In terms of braking, both bikes have double disk brakes at the front with four pistons. However, the Z1000 R has larger diameter disks (310 mm) and features radial, monoblock, and petal technology, which may provide better braking performance compared to the Z900's 300 mm double disk brakes with petal technology.

Both bikes have similar front and rear tire dimensions, with the Z900 having a front tire width of 120 mm and a rear tire width of 180 mm, while the Z1000 R has a front tire width of 120 mm and a rear tire width of 190 mm.

In terms of strengths, the Z900 is praised for its ingenious naked bike chassis, superb looks, and a perfectly dimensioned torque. It is also considered to be a good balance of performance, price, and practical use. On the other hand, the Z1000 R is praised for its powerful engine and high-quality chassis, providing a stable and precise ride. It is also known for offering a real naked bike feeling without the hecticness of a supersport bike.

In terms of weaknesses, the Z900 is criticized for having a narrow knee angle for tall people, suggesting that a different seat may be needed for more comfort. The Z1000 R is noted for having a little steering angle and lacking a shift assistant.

Overall, the Z1000 R offers more power and performance compared to the Z900, with a higher horsepower and torque rating. It also has more advanced suspension adjustments and a lighter aluminum frame. However, the Z900 may be more suitable for shorter riders due to its lower seat height.
