KTM 390 Duke (2025)

The KTM 390 Duke (2025) is listed in the Moto Kıyas database as a naked bike motorcycle with a 399 cc engine. The stored version is “Standart (Türkiye)”. According to manufacturer data it makes 44.4 hp and 39.0 Nm, with a wet weight of 165 kg. With a 75 kg rider the power-to-weight ratio is 184.9 hp/ton.

The Moto Kıyas physics model estimates 0-100 km/h (speedometer reading) in 5.48 s; because speedometers over-read, the true target is about 94.2 km/h. In a 100-0 km/h brake test it needs about 43.7 m of braking distance, or 52.0 m including a 0.3 s reaction time (with ABS). Calculated top speed is 167 km/h (test measurement). Among the 12 naked bike models in the database it ranks 4 of 12 for simulated 0-100 km/h and 4 of 12 for power-to-weight.

These figures are an estimated simulation, not a road-test measurement: flat dry asphalt, no wind, one 75 kg rider and no passenger. The model uses model-specific parameters calibrated against published road tests. Technical data comes from the sources listed below. In the app the results change with rider weight, a passenger, a wet surface or a slope.
