Honda CT125 Hunter Cub vs KTM 390 Duke

The Honda CT125 Hunter Cub (2026) 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 Honda CT125 Hunter Cub is a cub / underbone with 123 cc, 9.0 hp 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: 49.3 hp/ton versus 184.9 hp/ton. On this measure the KTM 390 Duke is 275% ahead.

0-100 km/h (speedometer): Honda CT125 Hunter Cub not reached (top simulated speed 89 km/h), KTM 390 Duke 5.48 s. In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 16.9 m for the Honda CT125 Hunter Cub (with ABS) and 15.7 m for the KTM 390 Duke (with ABS). The KTM 390 Duke stops 1.1 m shorter. The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 89 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 Honda CT125 Hunter Cub and model-specific parameters calibrated against published road tests for the KTM 390 Duke. 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.
