BMW S 1000 RR vs Harley-Davidson Sportster S

The BMW S 1000 RR (2025) and the Harley-Davidson Sportster S (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 Harley-Davidson Sportster S is a cruiser with 1,252 cc, 120.7 hp and 228 kg. Power-to-weight with the rider: 756.5 hp/ton versus 398.3 hp/ton. On this measure the BMW S 1000 RR is 90% ahead.

In the simulation the BMW S 1000 RR covers 0-100 km/h (speedometer) in 2.84 s and the Harley-Davidson Sportster S in 2.97 s; the BMW S 1000 RR is quicker by 0.13 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 44.7 m for the Harley-Davidson Sportster S (with ABS). The BMW S 1000 RR stops 8.3 m shorter. Calculated top speed: 287 km/h (manufacturer claim) versus 194 km/h (manufacturer claim).
