Is that an akrapovic?
Or is it only for the KRT edition? I swear i saw a video that claimed the 2017 got the akrapovic full system.
Akrapovic exhaust must be an option. Even the KRT does not come with it stock.
I believe Yamaha has factory Yoshimura option from dealer for R1(and other bikes?), Kawasaki has factory Akrapovic option for H2 so they might be extending that option to other bikes too.
