Always verify your motorcycle's model and year before purchase.

Mounting and Combinations

It mounts on the original headers or on the Arrow 71751MI stainless steel racing headers, which, however, do not bear the ECE mark: that configuration is for track use only.

For the same application, Arrow also offers the Race-Tech 71926AKN in Dark aluminum, the Race-Tech 71926PK in titanium, and the Works 71927PK in titanium. For the next generation of the S 1000 XR, there are the Indy Race EVO 77508PK and the Indy Race EVO 77508AKN.
