CFMoto 250NK vs KTM 500 EXC-F

The CFMoto 250NK (2026) and the KTM 500 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 CFMoto 250NK is a naked bike with 249 cc, 26.2 hp and unlisted weight; the KTM 500 EXC-F is a enduro bike with 511 cc, unlisted power and unlisted weight. Power-to-weight with the rider: 111.2 hp/ton versus no data.

In the simulation the CFMoto 250NK covers 0-100 km/h (speedometer) in 8.91 s and the KTM 500 EXC-F in 4.06 s; the KTM 500 EXC-F is quicker by 4.84 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 48.0 m for the CFMoto 250NK (ABS unknown, class assumption: no ABS) and 51.5 m for the KTM 500 EXC-F (ABS unknown, class assumption: no ABS). The CFMoto 250NK stops 3.4 m shorter. Calculated top speed: 115 km/h (estimated from power and drag) versus 158 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 CFMoto 250NK and class-average calibration (no accepted model-specific road test) for the KTM 500 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.
