Honda SH125i vs Honda Super Cub C125

The Honda SH125i (2025) and the Honda Super Cub C125 (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 Honda SH125i is a scooter with 125 cc, 12.9 hp and 138 kg; the Honda Super Cub C125 is a cub / underbone with 123 cc, 9.7 hp and unlisted weight. Power-to-weight with the rider: 60.4 hp/ton versus 53.0 hp/ton. On this measure the Honda SH125i is 14% ahead.

In the simulation the Honda SH125i covers 0-100 km/h (speedometer) in 19.13 s and the Honda Super Cub C125 in 39.63 s; the Honda SH125i is quicker by 20.50 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 Honda Super Cub C125 (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 93 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 Honda Super Cub C125. 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.
