Kawasaki Z900 vs KTM 450 EXC-F

The Kawasaki Z900 (2025) and the KTM 450 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 Kawasaki Z900 is a naked bike with 948 cc, 122.0 hp and 213 kg; the KTM 450 EXC-F is a enduro bike with 450 cc, unlisted power and unlisted weight. Power-to-weight with the rider: 423.7 hp/ton versus no data.

In the simulation the Kawasaki Z900 covers 0-100 km/h (speedometer) in 3.13 s and the KTM 450 EXC-F in 4.49 s; the Kawasaki Z900 is quicker by 1.36 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 43.7 m for the Kawasaki Z900 (with ABS) and 51.5 m for the KTM 450 EXC-F (ABS unknown, class assumption: no ABS). The Kawasaki Z900 stops 7.8 m shorter. Calculated top speed: 234 km/h (manufacturer claim) versus 151 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 Kawasaki Z900 and class-average calibration (no accepted model-specific road test) for the KTM 450 EXC-F. 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.
