BMW S 1000 RR vs Yamaha Exciter 155 VVA TCS

The BMW S 1000 RR (2025) and the Yamaha Exciter 155 VVA TCS (2026) 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 Exciter 155 VVA TCS is a cub / underbone with 155 cc, 18.2 hp and 124 kg. Power-to-weight with the rider: 756.5 hp/ton versus 91.7 hp/ton. On this measure the BMW S 1000 RR is 725% ahead.

In the simulation the BMW S 1000 RR covers 0-100 km/h (speedometer) in 2.84 s and the Yamaha Exciter 155 VVA TCS in 10.46 s; the BMW S 1000 RR is quicker by 7.63 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 46.8 m for the Yamaha Exciter 155 VVA TCS (with ABS). The BMW S 1000 RR stops 10.4 m shorter. Calculated top speed: 287 km/h (manufacturer claim) versus 115 km/h (estimated from power and drag).

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 the BMW S 1000 RR and class-average calibration (no accepted model-specific road test) for the Yamaha Exciter 155 VVA TCS.
