BMW K 1600 GT vs KTM 390 Duke

The BMW K 1600 GT (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 BMW K 1600 GT is a touring bike with 1,649 cc, 158.2 hp and 343 kg; the KTM 390 Duke is a naked bike with 399 cc, 44.4 hp and 165 kg. Power-to-weight with the rider: 378.6 hp/ton versus 184.9 hp/ton. On this measure the BMW K 1600 GT is 105% ahead.

In the simulation the BMW K 1600 GT covers 0-100 km/h (speedometer) in 3.27 s and the KTM 390 Duke in 5.48 s; the BMW K 1600 GT is quicker by 2.21 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 41.0 m for the BMW K 1600 GT (with ABS) and 43.7 m for the KTM 390 Duke (with ABS). The BMW K 1600 GT stops 2.7 m shorter. Calculated top speed: 226 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 BMW K 1600 GT and model-specific parameters calibrated against published road tests for the KTM 390 Duke.
