Harley-Davidson Breakout vs Honda Activa 125

The Harley-Davidson Breakout (2025) and the Honda Activa 125 (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 Breakout is a cruiser with 1,923 cc, 103.3 hp and 309 kg; the Honda Activa 125 is a scooter with 124 cc, 8.3 hp and 107 kg. Power-to-weight with the rider: 268.9 hp/ton versus 45.7 hp/ton. On this measure the Harley-Davidson Breakout is 489% ahead.

In the simulation the Harley-Davidson Breakout covers 0-100 km/h (speedometer) in 3.50 s and the Honda Activa 125 in 36.16 s; the Harley-Davidson Breakout is quicker by 32.66 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 Breakout (ABS unknown, class assumption: no ABS) and 17.9 m for the Honda Activa 125 (ABS unknown, class assumption: no ABS). The Harley-Davidson Breakout 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: 202 km/h (estimated from power and drag) versus 90 km/h (manufacturer claim).

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 Breakout and model-specific parameters calibrated against published road tests for the Honda Activa 125.
