ESTIMATED SIMULATION

Run the comparison →

The BMW S 1000 RR (2025) and the Yamaha XMAX 250 (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 S 1000 RR is a sport bike with 999 cc, 206.5 hp and 198 kg; the Yamaha XMAX 250 is a scooter with 250 cc, 22.4 hp and 183 kg. Power-to-weight with the rider: 756.5 hp/ton versus 86.8 hp/ton. On this measure the BMW S 1000 RR is 771% ahead.

In the simulation the BMW S 1000 RR covers 0-100 km/h (speedometer) in 2.84 s and the Yamaha XMAX 250 in 11.65 s; the BMW S 1000 RR is quicker by 8.81 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 36.4 m for the BMW S 1000 RR (with ABS) and 45.2 m for the Yamaha XMAX 250 (with ABS). The BMW S 1000 RR stops 8.8 m shorter. Calculated top speed: 287 km/h (manufacturer claim) versus 126 km/h (GPS measurement).

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.

Data sources and calibration

Specifications: the sources below (manufacturer pages, plus road-test or spec sites where the manufacturer gives no figure). Acceleration, braking and top speed: Moto Kıyas physics simulation (power/torque curve, gearing, drag, traction and wheelie limits, ABS assumption), calibrated against published road tests where available. Estimated, not measured.
