When it comes to choosing the perfect motorcycle, there are many factors to consider. One of the most important is deciding which model is ideal for your needs.

The Kawasaki zx6r and z900 are two bikes that are both popular choices for riders. However, they have their differences and similarities, which can make the decision process confusing.

Today we will compare and highlight the differences between the two models, helping you make an informed decision when choosing between these two.


One significant difference between the Kawasaki zx6r and z900 is their design. The zx6r is a sportbike with a sleek and aerodynamic body, making it perfect for performance enthusiasts.

The bike features a 636cc engine, and it comes with a number of advanced technologies such as LED headlights, quick shifter, and traction control.

On the other hand, the z900 is a naked bike with a muscular and aggressive stance. It has a 948cc engine and features a TFT LCD screen and four riding modes with Kawasaki’s IMU (Inertial Measurement Unit) which measures acceleration, pitch, and roll to provide data to the motorcycle’s aids. It is designed to provide comfort and stability while riding.


Performance is another essential factor that riders prioritize when choosing their bikes. The Kawasaki zx6r and z900 have different engine sizes that affect their performance.

The zx6r has a smaller engine size of 636cc and delivers 128 horsepower and 52.1 lb-ft of torque. It can reach a top speed of 155 mph, which is impressive, considering its size.

The z900, on the other hand, is equipped with a more massive 948cc engine that generates 123 horsepower and 72.6 lb-ft of torque. It can reach a top speed of 125 mph.

The z900 has a higher torque than the zx6r, which translates to more power at low speeds, making it an excellent bike for city riding.

Suspension and Brakes

The Kawasaki zx6r and z900 have different levels of suspension and braking systems. The zx6r has front inverted forks and a rear gas-charged shock, making it ideal for racing and aggressive riding. It also features a Brembo braking system that provides excellent stopping power.

The z900, on the other hand, has a non-adjustable 41mm upside-down fork at the front and a linked-shock rear suspension. Its brakes are also not as advanced as the zx6r, with dual 300mm discs at the front and a single 250mm disc at the back.

However, the z900 is designed to provide a comfortable and easy ride for daily commutes or long-distance journeys.


Price is an essential consideration for most riders, and it can significantly affect their choice of bike.

The Kawasaki zx6r is more expensive than the z900, with a starting price of around $11,999, while the z900 starts at around $8,999, making it a more affordable option.
