This is a full system constructed from a high-grade and race-proven lightweight titanium alloy that provides an impressive increase in power across the entire rev range while also improving torque delivery. The weight is decreased by over 5 kg. The system is finished with a hand-crafted carbon-fibre hexagonal muffler with a carbon-fibre endcap – inspired by Tom Sykes’s and Jonathan Rea's World Superbike–winning machine. A power increase in excess of 16 HP (12.1 kW) and a unique deeper, sporty sound enhance the system’s sporty heritage. An optional carbon-fibre muffler bracket is available to further complement the entire system. The bike’s ECU must be remapped when the Evolution Line system is installed.For perfect performance, throttle response, and durability, special mapping developed by Akrapovi?
