KTM 390 Duke vs KTM 450 EXC-F

The KTM 390 Duke (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 KTM 390 Duke is a naked bike with 399 cc, 44.4 hp and 165 kg; the KTM 450 EXC-F is a enduro bike with 450 cc, unlisted power and unlisted weight. Power-to-weight with the rider: 184.9 hp/ton versus no data.

In the simulation the KTM 390 Duke covers 0-100 km/h (speedometer) in 5.48 s and the KTM 450 EXC-F in 4.49 s; the KTM 450 EXC-F is quicker by 0.99 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 43.7 m for the KTM 390 Duke (with ABS) and 51.5 m for the KTM 450 EXC-F (ABS unknown, class assumption: no ABS). The KTM 390 Duke stops 7.8 m shorter. Calculated top speed: 167 km/h (test measurement) 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 KTM 390 Duke 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.
