Honda SH125i vs Honda Wave RSX FI

The Honda SH125i (2025) and the Honda Wave RSX FI (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 Wave RSX FI is a cub / underbone with 109 cc, 8.7 hp and unlisted weight. Power-to-weight with the rider: 60.4 hp/ton versus 49.5 hp/ton. On this measure the Honda SH125i is 22% ahead.

0-100 km/h (speedometer): Honda SH125i 19.13 s, Honda Wave RSX FI not reached (top simulated speed 88 km/h). 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 18.5 m for the Honda Wave RSX FI (ABS unknown, class assumption: no ABS). The Honda SH125i stops 2.2 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 88 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 Wave RSX FI. 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.
