Honda CBR650R vs KTM 390 Duke

ESTIMATED SIMULATION

Run the comparison →

The Honda CBR650R (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 CBR650R is a sport bike with 649 cc, 93.9 hp and 211 kg; the KTM 390 Duke is a naked bike with 399 cc, 44.4 hp and 165 kg. Power-to-weight with the rider: 328.2 hp/ton versus 184.9 hp/ton. On this measure the Honda CBR650R is 77% ahead.

In the simulation the Honda CBR650R covers 0-100 km/h (speedometer) in 3.33 s and the KTM 390 Duke in 5.48 s; the Honda CBR650R is quicker by 2.15 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 36.4 m for the Honda CBR650R (with ABS) and 43.7 m for the KTM 390 Duke (with ABS). The Honda CBR650R stops 7.3 m shorter. Calculated top speed: 220 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. Open the interactive app (currently in Turkish) to watch the run side by side and change the load.

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.
