BMW S 1000 RR vs Yamaha MT-25

The BMW S 1000 RR (2025) and the Yamaha MT-25 (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 MT-25 is a naked bike with 250 cc, 35.4 hp and 166 kg. Power-to-weight with the rider: 756.5 hp/ton versus 146.9 hp/ton. On this measure the BMW S 1000 RR is 415% ahead.

In the simulation the BMW S 1000 RR covers 0-100 km/h (speedometer) in 2.84 s and the Yamaha MT-25 in 6.35 s; the BMW S 1000 RR is quicker by 3.52 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 48.0 m for the Yamaha MT-25 (ABS unknown, class assumption: no ABS). The BMW S 1000 RR stops 11.6 m shorter. Calculated top speed: 287 km/h (manufacturer claim) versus 147 km/h (derived (GPS ratio)).

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.
