Honda Forza 250 vs Kawasaki Z900

The Honda Forza 250 (2026) and the Kawasaki Z900 (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 Honda Forza 250 is a scooter with 249 cc, 22.8 hp and 186 kg; the Kawasaki Z900 is a naked bike with 948 cc, 122.0 hp and 213 kg. Power-to-weight with the rider: 87.4 hp/ton versus 423.7 hp/ton. On this measure the Kawasaki Z900 is 385% ahead.

In the simulation the Honda Forza 250 covers 0-100 km/h (speedometer) in 10.05 s and the Kawasaki Z900 in 3.13 s; the Kawasaki Z900 is quicker by 6.92 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 45.2 m for the Honda Forza 250 (with ABS) and 43.7 m for the Kawasaki Z900 (with ABS). The Kawasaki Z900 stops 1.5 m shorter. Calculated top speed: 124 km/h (GPS measurement) versus 234 km/h (manufacturer claim).

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.
