Kawasaki Z900 2017 vs. KTM 790 Duke 2020

The Kawasaki Z900 2017 and the KTM 790 Duke 2020 are both naked bikes with inline engines and liquid cooling. However, there are several differences between the two models.

In terms of power, the Kawasaki Z900 2017 has a higher horsepower rating of 125.4 HP compared to the KTM 790 Duke 2020, which has 105 HP. This means that the Z900 may have better acceleration and overall performance.

Both bikes have fuel injection systems and four-cylinder engines, but the Z900 has a larger displacement of 948cc compared to the 799cc of the 790 Duke. This suggests that the Z900 may have more torque and a stronger low-end power delivery.

In terms of suspension, both bikes have upside-down telescopic forks at the front and a swingarm at the rear with a monoshock. However, the Z900 offers additional adjustability with both preload and recovery adjustments, while the 790 Duke only has preload adjustment. Both bikes have aluminum components in their suspension systems.

When it comes to the chassis, the Z900 has a steel frame with a double cradle design, while the 790 Duke features a chromium-molybdenum tubular frame. Both frames are designed to provide strength and stability, but the choice of materials may affect the overall weight and handling characteristics of the bikes.

In terms of braking, both bikes have dual disc brakes at the front with a diameter of 300mm and four-piston calipers. However, the 790 Duke features radial technology, which may provide better braking performance and feel compared to the petal technology used in the Z900.

In terms of advanced rider assistance systems, both bikes have ABS. However, the 790 Duke offers additional features such as riding modes and traction control, which can enhance the overall riding experience and safety.

In terms of dimensions, the Z900 has a narrower front tire width of 120mm compared to the 790 Duke's 120mm. Both bikes have the same rear tire width of 180mm. The Z900 has a slightly shorter wheelbase of 1450mm compared to the 790 Duke's 1475mm. The seat height of the Z900 is 795mm, while the 790 Duke has a higher seat height of 825mm.

In terms of strengths, the Z900 is praised for its clever naked bike chassis design, attractive appearance, responsive and torquey engine, and a good balance between performance, price, and practicality. On the other hand, the 790 Duke is praised for its high-revving twin-cylinder engine, quick-shifting lever, excellent chassis setup, playful handling, high-quality electronic package, TFT display, and good price-to-performance ratio.

However, there are also weaknesses to consider. The Z900 is criticized for having a narrow knee angle for taller riders, suggesting that a different seat may be needed. The 790 Duke's only weakness mentioned is that the rear suspension's spring preload is adjustable only, lacking recovery adjustment.

In conclusion, the Kawasaki Z900 2017 and the KTM 790 Duke 2020 are both impressive naked bikes with their own unique strengths and weaknesses. The Z900 offers more power and adjustability in the suspension, while the 790 Duke offers advanced electronic features and a high-revving twin-cylinder engine. Ultimately, the choice between the two models will depend on the rider's preferences and priorities.
