Kawasaki Ninja 500 vs RKS Neon125

The Kawasaki Ninja 500 (2026) and the RKS Neon125 (2026) 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 RKS Neon125 is a scooter with 125 cc, 9.3 hp and unlisted weight. Power-to-weight with the rider: 172.9 hp/ton versus 49.5 hp/ton. On this measure the Kawasaki Ninja 500 is 250% ahead.

0-100 km/h (speedometer): Kawasaki Ninja 500 5.09 s, RKS Neon125 not reached (top simulated speed 84 km/h). 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 RKS Neon125 (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 84 km/h (estimated from power and drag).

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 both. 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.
