KTM 390 Duke vs Yamaha Exciter 155 VVA TCS

The KTM 390 Duke (2025) and the Yamaha Exciter 155 VVA TCS (2026) 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 Yamaha Exciter 155 VVA TCS is a cub / underbone with 155 cc, 18.2 hp and 124 kg. Power-to-weight with the rider: 184.9 hp/ton versus 91.7 hp/ton. On this measure the KTM 390 Duke is 102% ahead.

In the simulation the KTM 390 Duke covers 0-100 km/h (speedometer) in 5.48 s and the Yamaha Exciter 155 VVA TCS in 10.46 s; the KTM 390 Duke is quicker by 4.98 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 46.8 m for the Yamaha Exciter 155 VVA TCS (with ABS). The KTM 390 Duke stops 3.1 m shorter. Calculated top speed: 167 km/h (test measurement) versus 115 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 the KTM 390 Duke and class-average calibration (no accepted model-specific road test) for the Yamaha Exciter 155 VVA TCS.
