KTM 390 Duke vs Kuba Superlight 125

The KTM 390 Duke (2025) and the Kuba Superlight 125 (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 Kuba Superlight 125 is a cruiser with 124 cc, 10.5 hp and unlisted weight. Power-to-weight with the rider: 184.9 hp/ton versus 42.5 hp/ton. On this measure the KTM 390 Duke is 335% ahead.

0-100 km/h (speedometer): KTM 390 Duke 5.48 s, Kuba Superlight 125 not reached (top simulated speed 91 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 17.7 m for the Kuba Superlight 125 (ABS unknown, class assumption: no ABS). The KTM 390 Duke stops 1.9 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 (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 Kuba Superlight 125.
