Kawasaki Ninja 500 vs Yamaha XMAX 250

The Kawasaki Ninja 500 (2026) and the Yamaha XMAX 250 (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 500 is a sport bike with 451 cc, 44.8 hp and unlisted weight; the Yamaha XMAX 250 is a scooter with 250 cc, 22.4 hp and 183 kg. Power-to-weight with the rider: 172.9 hp/ton versus 86.8 hp/ton. On this measure the Kawasaki Ninja 500 is 99% ahead.

In the simulation the Kawasaki Ninja 500 covers 0-100 km/h (speedometer) in 5.09 s and the Yamaha XMAX 250 in 11.65 s; the Kawasaki Ninja 500 is quicker by 6.56 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 36.4 m for the Kawasaki Ninja 500 (with ABS) and 45.2 m for the Yamaha XMAX 250 (with ABS). The Kawasaki Ninja 500 stops 8.8 m shorter. Calculated top speed: 186 km/h (estimated from power and drag) versus 126 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 500 and model-specific parameters calibrated against published road tests for the Yamaha XMAX 250. 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.
