Akrapovic Evolution systems are designed for riders who demand maximum performance from their motorcycle. Systems are significantly lighter if compared to stock exhaust system and feature exceptional production quality, hi-tech materials and of course increased engine performance combined with pure racing sound output. The Akrapovic Evolution systems were developed to complement the racing character of the R1. Evolution system is made entirely of our exclusive high grade titanium.

Difference to our standard Evolution system: (1) Headers with crossover same layout as EVO (2) Link pipe without fixing points for stock heat shield (3) Mufflers without db killers (4) Heat shields on the mufflers are made for racing and you cant fit stock one

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 12460 rpm we measured 165.7 HP, with max. increased power of 7.8 HP at 5900 rpm. The systems effect on the torque and power curve is huge and strongest in 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 much smoother ride.
