CFMoto 250NK vs Kawasaki Z900

The CFMoto 250NK (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 CFMoto 250NK is a naked bike with 249 cc, 26.2 hp and unlisted weight; the Kawasaki Z900 is a naked bike with 948 cc, 122.0 hp and 213 kg. Power-to-weight with the rider: 111.2 hp/ton versus 423.7 hp/ton. On this measure the Kawasaki Z900 is 281% ahead.

In the simulation the CFMoto 250NK covers 0-100 km/h (speedometer) in 8.91 s and the Kawasaki Z900 in 3.13 s; the Kawasaki Z900 is quicker by 5.78 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 48.0 m for the CFMoto 250NK (ABS unknown, class assumption: no ABS) and 43.7 m for the Kawasaki Z900 (with ABS). The Kawasaki Z900 stops 4.3 m shorter. Calculated top speed: 115 km/h (estimated from power and drag) 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.
