KTM 500 EXC-F vs Yamaha MT-25

The KTM 500 EXC-F (2025) and the Yamaha MT-25 (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 KTM 500 EXC-F is a enduro bike with 511 cc, unlisted power and unlisted weight; the Yamaha MT-25 is a naked bike with 250 cc, 35.4 hp and 166 kg. Power-to-weight with the rider: no data versus 146.9 hp/ton.

In the simulation the KTM 500 EXC-F covers 0-100 km/h (speedometer) in 4.06 s and the Yamaha MT-25 in 6.35 s; the KTM 500 EXC-F is quicker by 2.29 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 51.5 m for the KTM 500 EXC-F (ABS unknown, class assumption: no ABS) and 48.0 m for the Yamaha MT-25 (ABS unknown, class assumption: no ABS). The Yamaha MT-25 stops 3.4 m shorter. Calculated top speed: 158 km/h (estimated from power and drag) versus 147 km/h (derived (GPS ratio)).

All values are an estimated simulation, not road-test measurements. Technical data comes from the sources listed below; the model uses class-average calibration (no accepted model-specific road test) for the KTM 500 EXC-F and model-specific parameters calibrated against published road tests for the Yamaha MT-25. 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.
