KTM 250 EXC-F vs Yamaha XMAX 250

The KTM 250 EXC-F (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 KTM 250 EXC-F is a enduro bike with 250 cc, unlisted power and unlisted weight; the Yamaha XMAX 250 is a scooter with 250 cc, 22.4 hp and 183 kg. Power-to-weight with the rider: no data versus 86.8 hp/ton.

In the simulation the KTM 250 EXC-F covers 0-100 km/h (speedometer) in 7.92 s and the Yamaha XMAX 250 in 11.65 s; the KTM 250 EXC-F is quicker by 3.72 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 250 EXC-F (ABS unknown, class assumption: no ABS) and 45.2 m for the Yamaha XMAX 250 (with ABS). The Yamaha XMAX 250 stops 6.2 m shorter. Calculated top speed: 123 km/h (estimated from power and drag) 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 class-average calibration (no accepted model-specific road test) for the KTM 250 EXC-F and model-specific parameters calibrated against published road tests for the Yamaha XMAX 250. 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.
