CFMoto 250SR vs Harley-Davidson Street Bob

The CFMoto 250SR (2026) and the Harley-Davidson Street Bob (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 CFMoto 250SR is a sport bike with 249 cc, 26.2 hp and unlisted weight; the Harley-Davidson Street Bob is a cruiser with 1,923 cc, 91.2 hp and 293 kg. Power-to-weight with the rider: 105.1 hp/ton versus 247.8 hp/ton. On this measure the Harley-Davidson Street Bob is 136% ahead.

In the simulation the CFMoto 250SR covers 0-100 km/h (speedometer) in 8.38 s and the Harley-Davidson Street Bob in 3.49 s; the Harley-Davidson Street Bob is quicker by 4.88 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 36.4 m for the CFMoto 250SR (with ABS) and 49.1 m for the Harley-Davidson Street Bob (ABS unknown, class assumption: no ABS). The CFMoto 250SR stops 12.7 m shorter. Calculated top speed: 142 km/h (estimated from power and drag) versus 194 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 model-specific parameters calibrated against published road tests for the CFMoto 250SR and class-average calibration (no accepted model-specific road test) for the Harley-Davidson Street Bob.
