Harley-Davidson Street Bob vs Kawasaki Versys 650

The Harley-Davidson Street Bob (2025) and the Kawasaki Versys 650 (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 Kawasaki Versys 650 is a adventure bike with 649 cc, 65.7 hp and unlisted weight. Power-to-weight with the rider: 247.8 hp/ton versus 229.0 hp/ton. On this measure the Harley-Davidson Street Bob is 8% ahead.

In the simulation the Harley-Davidson Street Bob covers 0-100 km/h (speedometer) in 3.49 s and the Kawasaki Versys 650 in 3.79 s; the Harley-Davidson Street Bob is quicker by 0.29 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 41.4 m for the Kawasaki Versys 650 (with ABS). The Kawasaki Versys 650 stops 7.7 m shorter. Calculated top speed: 194 km/h (estimated from power and drag) versus 176 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 the Harley-Davidson Street Bob and model-specific parameters calibrated against published road tests for the Kawasaki Versys 650. 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.
