This is Part 4 of my review of the 2016 BMW S1000XR. If you haven’t already, be sure to read Part 1, Part 2, and Part 3.
Denali Split Dual-tone Horn
The Denali Dual-tone horn is a great replacement for the wimpy BMW horn. On my K1300S, I have the all-in-one version. S1000XR owners need the 2-piece version of the Denali Split Dual-tone Horn because space is tight in the S1000XR’s engine compartment. I also purchased the Denali S1000XR mounting brackets, the Denali plug and play cable, and the Denali wiring adapter for the horn.
Combining all three sets of instructions together:
- First, you need to remove the fairing on both sides of the S1000XR using a T25 screw driver. The screw is hidden inside the wheel well. The rest of the fairing then pops off.
- Then, remove the BMW OEM horn with the T30 screw driver.
- The Denali air compressor goes on the right side where your OEM horn was located. It is affixed by the Denali S1000XR compressor mounting bracket with a 13mm wrench. This is the painful part of the installation.
- The Denali trumpet goes on the left side, attached to the Denali S1000XR trumpet mounting bracket
- Connect the air hose between the air compressor and the trumpet. Route it away from the heat of the engine
- Connect the BMW OEM horn ground and positive wires to the Denali relay socket
- Connect the relay socket to the plug and play wiring harness
- Connect the wiring harness with the 30 Amp fuse to the battery
- Connect the wiring harness to the positive and ground on the Denali horn
- Use the zip ties to clean up and secure any excess wires
There’s a useful third-party installation video here.
