KTM 350 EXC-F vs Yamaha R25

The KTM 350 EXC-F (2025) and the Yamaha R25 (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 350 EXC-F is a enduro bike with 350 cc, unlisted power and unlisted weight; the Yamaha R25 is a sport bike with 250 cc, 35.4 hp and 169 kg. Power-to-weight with the rider: no data versus 145.1 hp/ton.

In the simulation the KTM 350 EXC-F covers 0-100 km/h (speedometer) in 5.62 s and the Yamaha R25 in 6.40 s; the KTM 350 EXC-F is quicker by 0.78 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 51.5 m for the KTM 350 EXC-F (ABS unknown, class assumption: no ABS) and 40.0 m for the Yamaha R25 (ABS unknown, class assumption: no ABS). The Yamaha R25 stops 11.4 m shorter. Calculated top speed: 138 km/h (estimated from power and drag) versus 158 km/h (GPS 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 KTM 350 EXC-F and model-specific parameters calibrated against published road tests for the Yamaha R25. Missing manufacturer data (power, torque, 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.
