Harley-Davidson Heritage Classic vs Honda PCX125

The Harley-Davidson Heritage Classic (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 Heritage Classic is a cruiser with 1,923 cc, 91.2 hp and 326 kg; the Honda PCX125 is a scooter with 125 cc, 12.3 hp and 134 kg. Power-to-weight with the rider: 227.4 hp/ton versus 59.0 hp/ton. On this measure the Harley-Davidson Heritage Classic is 285% ahead.

In the simulation the Harley-Davidson Heritage Classic covers 0-100 km/h (speedometer) in 3.78 s and the Honda PCX125 in 20.41 s; the Harley-Davidson Heritage Classic is quicker by 16.63 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 Heritage Classic (ABS unknown, class assumption: no ABS) and 16.3 m for the Honda PCX125 (with ABS). The Honda PCX125 stops 1.4 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 (estimated from power and drag) 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 class-average calibration (no accepted model-specific road test) for the Harley-Davidson Heritage Classic and model-specific parameters calibrated against published road tests for the Honda PCX125.
