Harley-Davidson Fat Boy vs Husqvarna FE 250

The Harley-Davidson Fat Boy (2025) and the Husqvarna FE 250 (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 Fat Boy is a cruiser with 1,923 cc, 103.3 hp and 315 kg; the Husqvarna FE 250 is a enduro bike with 250 cc, unlisted power and unlisted weight. Power-to-weight with the rider: 264.8 hp/ton versus no data.

In the simulation the Harley-Davidson Fat Boy covers 0-100 km/h (speedometer) in 3.54 s and the Husqvarna FE 250 in 7.92 s; the Harley-Davidson Fat Boy is quicker by 4.38 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 Fat Boy (ABS unknown, class assumption: no ABS) and 51.5 m for the Husqvarna FE 250 (ABS unknown, class assumption: no ABS). The Harley-Davidson Fat Boy stops 2.3 m shorter. Calculated top speed: 201 km/h (estimated from power and drag) versus 123 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 class-average calibration (no accepted model-specific road test) for both. Missing manufacturer data (power, torque, weight) is estimated by class regression, not measured. Open the interactive app (currently in Turkish) to watch the run side by side and change the load.
