Thanks for the dual horn shout out BMR. In addition to the horn upgrade I have also switched to LED turn signals, up and back bar risers because my arms are too short and OEM lowered suspension because my legs are too short. On the only modern bike I own, a 2017 BMW R9T, changing the engine mapping was essential as it ran very rough under 3000 rpm and did not pull smoothly until 4500 rpm. I went with a Power Commander Plug & Play which was pre-programmed for my aftermarket exhaust can. Huge difference. Not perfect but 97% improvement.
