Harley-Davidson Nightster Special vs Mondial 125 Drift L

The Harley-Davidson Nightster Special (2025) and the Mondial 125 Drift L (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 Harley-Davidson Nightster Special is a cruiser with 975 cc, 88.5 hp and 225 kg; the Mondial 125 Drift L is a naked bike with 124 cc, 10.7 hp and unlisted weight. Power-to-weight with the rider: 295.0 hp/ton versus 51.0 hp/ton. On this measure the Harley-Davidson Nightster Special is 478% ahead.

0-100 km/h (speedometer): Harley-Davidson Nightster Special 3.17 s, Mondial 125 Drift L not reached (top simulated speed 73 km/h). In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 17.7 m for the Harley-Davidson Nightster Special (ABS unknown, class assumption: no ABS) and 17.3 m for the Mondial 125 Drift L (ABS unknown, class assumption: no ABS). The Mondial 125 Drift L stops 0.4 m shorter. The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 180 km/h (estimated from power and drag) versus 90 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 model-specific parameters calibrated against published road tests for the Harley-Davidson Nightster Special and class-average calibration (no accepted model-specific road test) for the Mondial 125 Drift L. 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.
