Overview - Kawasaki Z900 RS 2018 vs Yamaha MT-09 2021

The Kawasaki Z900 RS 2018 and the Yamaha MT-09 2021 are both naked bikes with similar engine types and fuel systems. However, there are several key differences between the two models.

In terms of engine power, the Yamaha MT-09 2021 has a slight advantage with 119 HP compared to the Kawasaki Z900 RS 2018's 111 HP. However, the Kawasaki model has a higher torque of 98.6 Nm compared to the Yamaha's 93 Nm. This means that the Kawasaki may offer better acceleration and pulling power, while the Yamaha may have a smoother power delivery.

Both bikes have a liquid-cooled engine and a similar displacement, with the Kawasaki having a slightly larger engine at 948 ccm compared to the Yamaha's 889 ccm. This could result in a slightly higher top speed and overall performance for the Kawasaki.

In terms of suspension, both bikes feature upside-down telescopic forks at the front and a swing arm with a monoshock at the rear. This provides good stability and control for both models. However, the Yamaha MT-09 2021 has an aluminum frame compared to the steel frame of the Kawasaki Z900 RS 2018. This could result in a lighter overall weight for the Yamaha, which is reflected in its lower kerb weight of 189 kg compared to the Kawasaki's 215 kg.

Both bikes have double disk brakes at the front with similar diameters, providing good stopping power. The Kawasaki has a slightly larger fuel tank capacity at 17 liters compared to the Yamaha's 14 liters, which could result in a longer range.

In terms of rider assistance systems, both bikes feature ABS and traction control. However, the Yamaha MT-09 2021 also has a quickshifter, allowing for seamless gear changes without using the clutch. The Kawasaki Z900 RS 2018 does not have a shift assistant, which could be a disadvantage for riders looking for a more advanced riding experience.

In terms of dimensions, the Yamaha has a slightly shorter wheelbase at 1430 mm compared to the Kawasaki's 1470 mm. This could result in slightly different handling characteristics, with the Yamaha potentially offering more agility and maneuverability.

Both bikes have a comfortable seating position, but the Kawasaki Z900 RS 2018 has been praised for its ergonomics and comfortable ride on long tours. However, the seat on the Kawasaki may be considered too soft by some riders. The Yamaha MT-09 2021 also offers a comfortably integrated seating position and has been praised for its lively handling and riding pleasure.

In terms of aesthetics, the Kawasaki Z900 RS 2018 is known for its good looks and retro styling, while the Yamaha MT-09 2021 has a more polarizing look that may not appeal to everyone.

Overall, the Kawasaki Z900 RS 2018 and the Yamaha MT-09 2021 are both capable naked bikes with their own strengths and weaknesses. The Kawasaki offers a powerful and smooth engine, comfortable seating position, and balanced handling. However, it may be heavier than other retro bikes in its class and lacks a shift assistant. On the other hand, the Yamaha offers even more pressure from the center, an over-complete electronics package, and a great working quickshifter. It also has a lighter weight and a more agile handling, but its polarizing look and limited front wheel feel may not appeal to everyone.

The ingredients for the 2021 update are right: More power, more equipment, more electronics, less weight. If you take a look at the key data of the latest MT-09, including its over-complete standard equipment, "mid-range naked bike" almost sounds a bit pejorative. The Japanese engineers have made improvements exactly where they were needed. The swaying chassis is now a thing of the past and the load change reactions have also been eliminated from the revised three-cylinder engine. The additional power paired with a little more pressure in the mid-range gives a sovereign riding feeling. The MT-09 offers a lot of equipment and enormous riding pleasure at a very attractive price. If you like the look, you can buy it without hesitation.
