Honda CB125F vs Honda SH125i

The Honda CB125F (2025) and the Honda SH125i (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 CB125F is a naked bike with 124 cc, 10.7 hp and 117 kg; the Honda SH125i is a scooter with 125 cc, 12.9 hp and 138 kg. Power-to-weight with the rider: 55.9 hp/ton versus 60.4 hp/ton. On this measure the Honda SH125i is 8% ahead.

In the simulation the Honda CB125F covers 0-100 km/h (speedometer) in 21.61 s and the Honda SH125i in 19.13 s; the Honda SH125i is quicker by 2.47 s. In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 17.3 m for the Honda CB125F (ABS unknown, class assumption: no ABS) and 16.3 m for the Honda SH125i (with ABS). The Honda SH125i stops 1.0 m shorter. The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 100 km/h (manufacturer claim) versus 97 km/h (manufacturer claim).

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 both.
