KTM 350 EXC-F vs KTM 390 Duke

The KTM 350 EXC-F (2025) and the KTM 390 Duke (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 350 EXC-F is a enduro bike with 350 cc, unlisted power and unlisted weight; the KTM 390 Duke is a naked bike with 399 cc, 44.4 hp and 165 kg. Power-to-weight with the rider: no data versus 184.9 hp/ton.

In the simulation the KTM 350 EXC-F covers 0-100 km/h (speedometer) in 5.62 s and the KTM 390 Duke in 5.48 s; the KTM 390 Duke is quicker by 0.14 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 350 EXC-F (ABS unknown, class assumption: no ABS) and 43.7 m for the KTM 390 Duke (with ABS). The KTM 390 Duke stops 7.8 m shorter. Calculated top speed: 138 km/h (estimated from power and drag) versus 167 km/h (test 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 350 EXC-F and model-specific parameters calibrated against published road tests for the KTM 390 Duke. 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.
