Harley-Davidson Nightster Special vs Honda Wave RSX FI

The Harley-Davidson Nightster Special (2025) and the Honda Wave RSX FI (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 Wave RSX FI is a cub / underbone with 109 cc, 8.7 hp and unlisted weight. Power-to-weight with the rider: 295.0 hp/ton versus 49.5 hp/ton. On this measure the Harley-Davidson Nightster Special is 496% ahead.

0-100 km/h (speedometer): Harley-Davidson Nightster Special 3.17 s, Honda Wave RSX FI not reached (top simulated speed 88 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 18.5 m for the Honda Wave RSX FI (ABS unknown, class assumption: no ABS). The Harley-Davidson Nightster Special 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 88 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 Wave RSX FI. 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.
