Performance
Measurements of the Akrapovic EVOLUTION system on the BMW S 1000 RR (without muffler insert):
Power & Torque: The power increase with the Akrapovic system is substantial, and can be seen from 7000 rpm right to the top of the range. At 13270 rpm we measured 191.30 HP, with a max. power increase of 11.15 HP at 8450 rpm. The system’s effect on the torque and power curve is huge and strongest at midrange rpm. The main increase starts at around 4500 rpm and continues right into the over-rev range. All this will help you shave lap times and result in a much smoother ride.
