Harley-Davidson Sportster S vs Honda PCX125

The Harley-Davidson Sportster S (2025) and the Honda PCX125 (2025) 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 PCX125 is a scooter with 125 cc, 12.3 hp and 134 kg. Power-to-weight with the rider: 398.3 hp/ton versus 59.0 hp/ton. On this measure the Harley-Davidson Sportster S is 575% ahead.

In the simulation the Harley-Davidson Sportster S covers 0-100 km/h (speedometer) in 2.97 s and the Honda PCX125 in 20.41 s; the Harley-Davidson Sportster S is quicker by 17.44 s. In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 16.1 m for the Harley-Davidson Sportster S (with ABS) and 16.3 m for the Honda PCX125 (with ABS). The Harley-Davidson Sportster S stops 0.2 m shorter. The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 194 km/h (manufacturer claim) versus 92 km/h (GPS measurement).

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 both.
