Harley-Davidson Street Bob vs Honda CRF250 Rally

The Harley-Davidson Street Bob (2025) and the Honda CRF250 Rally (2026) 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 Honda CRF250 Rally is a enduro bike with 249 cc, 24.1 hp and 153 kg. Power-to-weight with the rider: 247.8 hp/ton versus 105.9 hp/ton. On this measure the Harley-Davidson Street Bob is 134% ahead.

In the simulation the Harley-Davidson Street Bob covers 0-100 km/h (speedometer) in 3.49 s and the Honda CRF250 Rally in 7.61 s; the Harley-Davidson Street Bob is quicker by 4.12 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 46.8 m for the Honda CRF250 Rally (with ABS). The Honda CRF250 Rally 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.
