BMW R 1300 RT vs Kawasaki Z900

The BMW R 1300 RT (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 BMW R 1300 RT is a touring bike with 1,300 cc, 143.5 hp and 281 kg; the Kawasaki Z900 is a naked bike with 948 cc, 122.0 hp and 213 kg. Power-to-weight with the rider: 403.1 hp/ton versus 423.7 hp/ton. On this measure the Kawasaki Z900 is 5% ahead.

In the simulation the BMW R 1300 RT covers 0-100 km/h (speedometer) in 3.37 s and the Kawasaki Z900 in 3.13 s; the Kawasaki Z900 is quicker by 0.24 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 41.0 m for the BMW R 1300 RT (with ABS) and 43.7 m for the Kawasaki Z900 (with ABS). The BMW R 1300 RT stops 2.7 m shorter. Calculated top speed: 229 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.
