Harley-Davidson Heritage Classic vs Suzuki DR-Z4S

The Harley-Davidson Heritage Classic (2025) and the Suzuki DR-Z4S (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 Heritage Classic is a cruiser with 1,923 cc, 91.2 hp and 326 kg; the Suzuki DR-Z4S is a enduro bike with 398 cc, unlisted power and 151 kg. Power-to-weight with the rider: 227.4 hp/ton versus no data.

In the simulation the Harley-Davidson Heritage Classic covers 0-100 km/h (speedometer) in 3.78 s and the Suzuki DR-Z4S in 4.98 s; the Harley-Davidson Heritage Classic is quicker by 1.20 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 Heritage Classic (ABS unknown, class assumption: no ABS) and 46.8 m for the Suzuki DR-Z4S (with ABS). The Suzuki DR-Z4S stops 2.3 m shorter. Calculated top speed: 194 km/h (estimated from power and drag) versus 145 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) 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.
