Harley-Davidson Nightster Special vs Honda Super Cub C125

The Harley-Davidson Nightster Special (2025) and the Honda Super Cub C125 (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 Honda Super Cub C125 is a cub / underbone with 123 cc, 9.7 hp and unlisted weight. Power-to-weight with the rider: 295.0 hp/ton versus 53.0 hp/ton. On this measure the Harley-Davidson Nightster Special is 456% ahead.

In the simulation the Harley-Davidson Nightster Special covers 0-100 km/h (speedometer) in 3.17 s and the Honda Super Cub C125 in 39.63 s; the Harley-Davidson Nightster Special is quicker by 36.46 s. 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 16.9 m for the Honda Super Cub C125 (with ABS). The Honda Super Cub C125 stops 0.8 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 93 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 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 Honda Super Cub C125. 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.
