Harley-Davidson Street Bob vs KTM 250 EXC-F

The Harley-Davidson Street Bob (2025) and the KTM 250 EXC-F (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 Street Bob is a cruiser with 1,923 cc, 91.2 hp and 293 kg; the KTM 250 EXC-F is a enduro bike with 250 cc, unlisted power and unlisted weight. Power-to-weight with the rider: 247.8 hp/ton versus no data.

In the simulation the Harley-Davidson Street Bob covers 0-100 km/h (speedometer) in 3.49 s and the KTM 250 EXC-F in 7.92 s; the Harley-Davidson Street Bob is quicker by 4.43 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 Street Bob (ABS unknown, class assumption: no ABS) and 51.5 m for the KTM 250 EXC-F (ABS unknown, class assumption: no ABS). The Harley-Davidson Street Bob stops 2.3 m shorter. Calculated top speed: 194 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.
