Harley-Davidson Nightster Special vs Honda GL1800 Gold Wing

The Harley-Davidson Nightster Special (2025) and the Honda GL1800 Gold Wing (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 GL1800 Gold Wing is a touring bike with 1,833 cc, 124.7 hp and 393 kg. Power-to-weight with the rider: 295.0 hp/ton versus 266.5 hp/ton. On this measure the Harley-Davidson Nightster Special is 11% ahead.

In the simulation the Harley-Davidson Nightster Special covers 0-100 km/h (speedometer) in 3.17 s and the Honda GL1800 Gold Wing in 4.46 s; the Harley-Davidson Nightster Special is quicker by 1.29 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 49.1 m for the Harley-Davidson Nightster Special (ABS unknown, class assumption: no ABS) and 41.0 m for the Honda GL1800 Gold Wing (with ABS). The Honda GL1800 Gold Wing stops 8.1 m shorter. Calculated top speed: 180 km/h (estimated from power and drag) versus 207 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 GL1800 Gold Wing.
