Kawasaki Ninja 1100SX SE vs Yamaha R25

The Kawasaki Ninja 1100SX SE (2026) and the Yamaha R25 (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 Yamaha R25 is a sport bike with 250 cc, 35.4 hp and 169 kg. Power-to-weight with the rider: 409.9 hp/ton versus 145.1 hp/ton. On this measure the Kawasaki Ninja 1100SX SE is 183% ahead.

In the simulation the Kawasaki Ninja 1100SX SE covers 0-100 km/h (speedometer) in 3.30 s and the Yamaha R25 in 6.40 s; the Kawasaki Ninja 1100SX SE is quicker by 3.10 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 40.0 m for the Yamaha R25 (ABS unknown, class assumption: no ABS). The Yamaha R25 stops 1.0 m shorter. Calculated top speed: 219 km/h (estimated from power and drag) versus 158 km/h (GPS measurement).

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 Yamaha R25. 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.
