Honda Activa 125 vs KTM 390 Duke

ESTIMATED SIMULATION

Run the comparison →

The Honda Activa 125 (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 Honda Activa 125 is a scooter with 124 cc, 8.3 hp and 107 kg; the KTM 390 Duke is a naked bike with 399 cc, 44.4 hp and 165 kg. Power-to-weight with the rider: 45.7 hp/ton versus 184.9 hp/ton. On this measure the KTM 390 Duke is 305% ahead.

In the simulation the Honda Activa 125 covers 0-100 km/h (speedometer) in 36.16 s and the KTM 390 Duke in 5.48 s; the KTM 390 Duke is quicker by 30.68 s. In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 17.9 m for the Honda Activa 125 (ABS unknown, class assumption: no ABS) and 15.7 m for the KTM 390 Duke (with ABS). The KTM 390 Duke stops 2.2 m shorter. The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 90 km/h (manufacturer claim) 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 model-specific parameters calibrated against published road tests for both.

Data sources and calibration

Specifications: the sources below (manufacturer pages, plus road-test or spec sites where the manufacturer gives no figure). Acceleration, braking and top speed: Moto Kıyas physics simulation (power/torque curve, gearing, drag, traction and wheelie limits, ABS assumption), calibrated against published road tests where available. Estimated, not measured.
