Kawasaki Ninja 500 vs Yamaha NMAX 125

The Kawasaki Ninja 500 (2026) and the Yamaha NMAX 125 (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 NMAX 125 is a scooter with 125 cc, 12.1 hp and 132 kg. Power-to-weight with the rider: 172.9 hp/ton versus 58.3 hp/ton. On this measure the Kawasaki Ninja 500 is 197% ahead.

In the simulation the Kawasaki Ninja 500 covers 0-100 km/h (speedometer) in 5.09 s and the Yamaha NMAX 125 in 20.34 s; the Kawasaki Ninja 500 is quicker by 15.25 s. In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 13.1 m for the Kawasaki Ninja 500 (with ABS) and 17.9 m for the Yamaha NMAX 125 (ABS unknown, class assumption: no ABS). The Kawasaki Ninja 500 stops 4.8 m shorter. The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 186 km/h (estimated from power and drag) versus 99 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 NMAX 125. 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.
