Kawasaki Vulcan S vs Suzuki DR-Z4S

The Kawasaki Vulcan S (2026) 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 Kawasaki Vulcan S is a cruiser with 649 cc, 59.9 hp and unlisted weight; the Suzuki DR-Z4S is a enduro bike with 398 cc, unlisted power and 151 kg. Power-to-weight with the rider: 226.5 hp/ton versus no data.

In the simulation the Kawasaki Vulcan S covers 0-100 km/h (speedometer) in 4.49 s and the Suzuki DR-Z4S in 4.98 s; the Kawasaki Vulcan S is quicker by 0.50 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 44.7 m for the Kawasaki Vulcan S (with ABS) and 46.8 m for the Suzuki DR-Z4S (with ABS). The Kawasaki Vulcan S stops 2.1 m shorter. Calculated top speed: 173 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 model-specific parameters calibrated against published road tests for the Kawasaki Vulcan S and class-average calibration (no accepted model-specific road test) for the Suzuki DR-Z4S. Missing manufacturer data (weight) is estimated by class regression, not measured. Missing manufacturer data (power, torque) is estimated by class regression, not measured.
