Honda SH125i vs Suzuki DR-Z4S

The Honda SH125i (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 Honda SH125i is a scooter with 125 cc, 12.9 hp and 138 kg; the Suzuki DR-Z4S is a enduro bike with 398 cc, unlisted power and 151 kg. Power-to-weight with the rider: 60.4 hp/ton versus no data.

In the simulation the Honda SH125i covers 0-100 km/h (speedometer) in 19.13 s and the Suzuki DR-Z4S in 4.98 s; the Suzuki DR-Z4S is quicker by 14.15 s. In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 16.3 m for the Honda SH125i (with ABS) and 16.9 m for the Suzuki DR-Z4S (with ABS). The Honda SH125i stops 0.6 m shorter. The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 97 km/h (manufacturer claim) 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 Honda SH125i and class-average calibration (no accepted model-specific road test) for the Suzuki DR-Z4S. 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.
