Overview - Kawasaki Z650 2017 vs Kawasaki Z900 2017

The Kawasaki Z650 2017 and the Kawasaki Z900 2017 are both naked bikes with similar engine types, fuel systems, and cooling systems. However, there are several key differences between the two models.

In terms of engine power, the Z650 has 68.2 HP, while the Z900 boasts a more powerful 125.4 HP. The Z900 also has a higher torque of 98.6 Nm compared to the Z650's 65.7 Nm. This means that the Z900 offers more acceleration and overall power, making it suitable for riders who crave a more thrilling and dynamic riding experience.

Both bikes feature a swing arm rear suspension with a monoshock, but the Z650 only has preload adjustment, while the Z900 has both preload and rebound adjustment. This allows riders to fine-tune the suspension to their preferences and riding style. Additionally, the Z900 has an upside-down telescopic fork for the front suspension, which provides better stability and control during aggressive riding.

The chassis of both bikes is made of steel, but the Z900 has a double cradle frame, which offers improved rigidity and handling compared to the tubular frame of the Z650. This makes the Z900 more stable and responsive in corners and at higher speeds.

When it comes to braking, both bikes have double disk brakes at the front with a diameter of 300 mm. However, the Z900 has four-piston calipers, providing better stopping power and control compared to the Z650's double-piston calipers. Both bikes also feature ABS as an advanced rider assistance system, ensuring safe and controlled braking in various conditions.

In terms of dimensions and weights, the Z900 has a slightly larger wheelbase of 1450 mm compared to the Z650's 1410 mm. The Z900 also has a slightly higher seat height of 795 mm, which may be less comfortable for taller riders. However, both bikes have similar front and rear tire dimensions, with the Z900 having a slightly wider rear tire of 180 mm compared to the Z650's 160 mm. The Z900 is also slightly heavier, with a kerb weight of 210 kg compared to the Z650's 187.1 kg.

In terms of strengths, the Z650 offers even power delivery, a sporty chassis, compact dimensions, and a negative display. On the other hand, the Z900 is praised for its ingenious naked bike chassis, superb looks, responsive engine with perfectly dimensioned torque, and its optimum intersection of performance, price, and practical use.

In terms of weaknesses, the Z650 is considered a little too small for tall people, while the Z900 has a narrow knee angle for taller riders. However, this can be addressed by ordering a different seat for the Z900.

Overall, the Kawasaki Z650 2017 is a capable and enjoyable naked bike with good power and handling, suitable for riders of various heights. The Kawasaki Z900 2017, on the other hand, offers a more powerful engine, improved suspension adjustability, and a more rigid chassis, making it a more performance-oriented option, albeit with some considerations for taller riders.

Pros and Cons in comparison

Kawasaki Z650 2017

Kawasaki Z650 2017

The Kawasaki Z 650 is the tip of the middle class for small male and female riders. On its compact dimensions, you probably won't feel comfortable as a giant. Heart-warming feelings, however, come from the engine, which delights with a very smooth pull. On the chassis side, a Kawasaki-typical tight set-up was chosen, which finds a great compromise in everyday use. The negative display is very easy to read and is reminiscent of its predecessor, the ER-6n - very nice!
