Kawasaki Z900 vs Yamaha MT-09

The Kawasaki Z900 (2025) and the Yamaha MT-09 (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 Yamaha MT-09 is a naked bike with 890 cc, 117.3 hp and 193 kg. Power-to-weight with the rider: 423.7 hp/ton versus 437.8 hp/ton. On this measure the Yamaha MT-09 is 3% ahead.

In the simulation the Kawasaki Z900 covers 0-100 km/h (speedometer) in 3.13 s and the Yamaha MT-09 in 3.11 s; the Yamaha MT-09 is quicker by 0.02 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 48.0 m for the Yamaha MT-09 (ABS unknown, class assumption: no ABS). The Kawasaki Z900 stops 4.3 m shorter. Calculated top speed: 234 km/h (manufacturer claim) versus 199 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.
