Harley-Davidson Street Bob vs Mondial Fuzion 125

The Harley-Davidson Street Bob (2025) and the Mondial Fuzion 125 (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 Mondial Fuzion 125 is a scooter with 124 cc, 9.1 hp and unlisted weight. Power-to-weight with the rider: 247.8 hp/ton versus 46.3 hp/ton. On this measure the Harley-Davidson Street Bob is 436% ahead.

0-100 km/h (speedometer): Harley-Davidson Street Bob 3.49 s, Mondial Fuzion 125 not reached (top simulated speed 69 km/h). 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 Street Bob (ABS unknown, class assumption: no ABS) and 17.9 m for the Mondial Fuzion 125 (ABS unknown, class assumption: no ABS). The Harley-Davidson Street Bob 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: 194 km/h (estimated from power and drag) versus 80 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 both. Missing manufacturer data (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.
