Honda GL1800 Gold Wing vs KTM 390 Duke

The Honda GL1800 Gold Wing (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 GL1800 Gold Wing is a touring bike with 1,833 cc, 124.7 hp and 393 kg; the KTM 390 Duke is a naked bike with 399 cc, 44.4 hp and 165 kg. Power-to-weight with the rider: 266.5 hp/ton versus 184.9 hp/ton. On this measure the Honda GL1800 Gold Wing is 44% ahead.

In the simulation the Honda GL1800 Gold Wing covers 0-100 km/h (speedometer) in 4.46 s and the KTM 390 Duke in 5.48 s; the Honda GL1800 Gold Wing is quicker by 1.02 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 41.0 m for the Honda GL1800 Gold Wing (with ABS) and 43.7 m for the KTM 390 Duke (with ABS). The Honda GL1800 Gold Wing stops 2.7 m shorter. Calculated top speed: 207 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 GL1800 Gold Wing and model-specific parameters calibrated against published road tests for the KTM 390 Duke.
