Yamaha R1 Akrapovic Evolution Full Exhaust Carbon Mufflers
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.
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 system’s
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.
