KTM 450 EXC-F vs KTM 500 EXC-F

The KTM 450 EXC-F (2025) and the KTM 500 EXC-F (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 450 EXC-F is a enduro bike with 450 cc, unlisted power and unlisted weight; the KTM 500 EXC-F is a enduro bike with 511 cc, unlisted power and unlisted weight. Power-to-weight with the rider: no data versus no data.

In the simulation the KTM 450 EXC-F covers 0-100 km/h (speedometer) in 4.49 s and the KTM 500 EXC-F in 4.06 s; the KTM 500 EXC-F is quicker by 0.43 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 450 EXC-F (ABS unknown, class assumption: no ABS) and 51.5 m for the KTM 500 EXC-F (ABS unknown, class assumption: no ABS). Calculated top speed: 151 km/h (estimated from power and drag) versus 158 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 class-average calibration (no accepted model-specific road test) for both. Missing manufacturer data (power, torque, weight) is estimated by class regression, not measured. Missing manufacturer data (power, torque, weight) is estimated by class regression, not measured.
