Harley-Davidson Sportster S vs Honda GL1800 Gold Wing

The Harley-Davidson Sportster S (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 Sportster S is a cruiser with 1,252 cc, 120.7 hp and 228 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: 398.3 hp/ton versus 266.5 hp/ton. On this measure the Harley-Davidson Sportster S is 49% ahead.

In the simulation the Harley-Davidson Sportster S covers 0-100 km/h (speedometer) in 2.97 s and the Honda GL1800 Gold Wing in 4.46 s; the Harley-Davidson Sportster S is quicker by 1.49 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 44.7 m for the Harley-Davidson Sportster S (with ABS) and 41.0 m for the Honda GL1800 Gold Wing (with ABS). The Honda GL1800 Gold Wing stops 3.7 m shorter. Calculated top speed: 194 km/h (manufacturer claim) 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 Sportster S and class-average calibration (no accepted model-specific road test) for the Honda GL1800 Gold Wing.
