Honda SH125i vs Yamaha XMAX 250

The Honda SH125i (2025) and the Yamaha XMAX 250 (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 Yamaha XMAX 250 is a scooter with 250 cc, 22.4 hp and 183 kg. Power-to-weight with the rider: 60.4 hp/ton versus 86.8 hp/ton. On this measure the Yamaha XMAX 250 is 44% ahead.

In the simulation the Honda SH125i covers 0-100 km/h (speedometer) in 19.13 s and the Yamaha XMAX 250 in 11.65 s; the Yamaha XMAX 250 is quicker by 7.49 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 16.3 m for the Yamaha XMAX 250 (with ABS). 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 126 km/h (GPS measurement).

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.
