Kawasaki Ninja 1100SX SE vs Kawasaki Z900

The Kawasaki Ninja 1100SX SE (2026) and the Kawasaki Z900 (2025) are compared with the same Moto Kıyas physics model under identical conditions: flat dry asphalt, no wind, a 75 kg rider and no passenger. The Kawasaki Ninja 1100SX SE is a touring bike with 1,099 cc, 134.1 hp and unlisted weight; the Kawasaki Z900 is a naked bike with 948 cc, 122.0 hp and 213 kg. Power-to-weight with the rider: 409.9 hp/ton versus 423.7 hp/ton. On this measure the Kawasaki Z900 is 3% ahead.

In the simulation the Kawasaki Ninja 1100SX SE covers 0-100 km/h (speedometer) in 3.30 s and the Kawasaki Z900 in 3.13 s; the Kawasaki Z900 is quicker by 0.17 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 41.0 m for the Kawasaki Ninja 1100SX SE (with ABS) and 43.7 m for the Kawasaki Z900 (with ABS). The Kawasaki Ninja 1100SX SE stops 2.7 m shorter. Calculated top speed: 219 km/h (estimated from power and drag) versus 234 km/h (manufacturer claim).

All values are an estimated simulation, not road-test measurements. Technical data comes from the sources listed below; the model uses class-average calibration (no accepted model-specific road test) for the Kawasaki Ninja 1100SX SE and model-specific parameters calibrated against published road tests for the Kawasaki Z900. Missing manufacturer data (weight) is estimated by class regression, not measured. Open the interactive app (currently in Turkish) to watch the run side by side and change the load.
