KTM 390 Duke vs Mondial 125 Drift L

The KTM 390 Duke (2025) and the Mondial 125 Drift L (2026) 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 Mondial 125 Drift L is a naked bike with 124 cc, 10.7 hp and unlisted weight. Power-to-weight with the rider: 184.9 hp/ton versus 51.0 hp/ton. On this measure the KTM 390 Duke is 262% ahead.

0-100 km/h (speedometer): KTM 390 Duke 5.48 s, Mondial 125 Drift L not reached (top simulated speed 73 km/h). In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 15.7 m for the KTM 390 Duke (with ABS) and 17.3 m for the Mondial 125 Drift L (ABS unknown, class assumption: no ABS). The KTM 390 Duke stops 1.6 m shorter. The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 167 km/h (test measurement) versus 90 km/h (manufacturer claim).

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 Mondial 125 Drift L. Missing manufacturer data (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.
