Honda CBR1000RR-R Fireblade SP vs Kawasaki Z900

The Honda CBR1000RR-R Fireblade SP (2025) 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 CBR1000RR-R Fireblade SP is a sport bike with 1,000 cc, 214.6 hp and 201 kg; the Kawasaki Z900 is a naked bike with 948 cc, 122.0 hp and 213 kg. Power-to-weight with the rider: 777.4 hp/ton versus 423.7 hp/ton. On this measure the Honda CBR1000RR-R Fireblade SP is 83% ahead.

In the simulation the Honda CBR1000RR-R Fireblade SP covers 0-100 km/h (speedometer) in 2.96 s and the Kawasaki Z900 in 3.13 s; the Honda CBR1000RR-R Fireblade SP is quicker by 0.17 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 36.4 m for the Honda CBR1000RR-R Fireblade SP (with ABS) and 43.7 m for the Kawasaki Z900 (with ABS). The Honda CBR1000RR-R Fireblade SP stops 7.3 m shorter. Calculated top speed: 315 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 class-average calibration (no accepted model-specific road test) for the Honda CBR1000RR-R Fireblade SP and model-specific parameters calibrated against published road tests for the Kawasaki Z900.
