Honda SH125i vs KTM 450 EXC-F

The Honda SH125i (2025) and the KTM 450 EXC-F (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 KTM 450 EXC-F is a enduro bike with 450 cc, unlisted power and unlisted weight. 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 KTM 450 EXC-F in 4.49 s; the KTM 450 EXC-F is quicker by 14.64 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 18.5 m for the KTM 450 EXC-F (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 151 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 KTM 450 EXC-F. Missing manufacturer data (power, torque, 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.
