KTM 390 Duke vs Suzuki V-Strom 1050 DE

The KTM 390 Duke (2025) and the Suzuki V-Strom 1050 DE (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 KTM 390 Duke is a naked bike with 399 cc, 44.4 hp and 165 kg; the Suzuki V-Strom 1050 DE is a adventure bike with 1,037 cc, 105.9 hp and unlisted weight. Power-to-weight with the rider: 184.9 hp/ton versus 341.1 hp/ton. On this measure the Suzuki V-Strom 1050 DE is 84% ahead.

In the simulation the KTM 390 Duke covers 0-100 km/h (speedometer) in 5.48 s and the Suzuki V-Strom 1050 DE in 3.12 s; the Suzuki V-Strom 1050 DE is quicker by 2.36 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 43.7 m for the KTM 390 Duke (with ABS) and 41.4 m for the Suzuki V-Strom 1050 DE (with ABS). The Suzuki V-Strom 1050 DE stops 2.3 m shorter. Calculated top speed: 167 km/h (test measurement) versus 194 km/h (estimated from power and drag).

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. Missing manufacturer data (weight) is estimated by class regression, not measured. Open the interactive app (currently in Turkish) to watch the run side by side and change the load.
