BMW S 1000 RR vs Yamaha R25

ESTIMATED SIMULATION

Run the comparison →

The BMW S 1000 RR (2025) and the Yamaha R25 (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 R25 is a sport bike with 250 cc, 35.4 hp and 169 kg. Power-to-weight with the rider: 756.5 hp/ton versus 145.1 hp/ton. On this measure the BMW S 1000 RR is 421% ahead.

In the simulation the BMW S 1000 RR covers 0-100 km/h (speedometer) in 2.84 s and the Yamaha R25 in 6.40 s; the BMW S 1000 RR is quicker by 3.57 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 40.0 m for the Yamaha R25 (ABS unknown, class assumption: no ABS). The BMW S 1000 RR stops 3.6 m shorter. Calculated top speed: 287 km/h (manufacturer claim) versus 158 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. Open the interactive app (currently in Turkish) to watch the run side by side and change the load.

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.
