Welcome, I tinker as well, I've got a 2015 S1000RR. I've got a heard jacket, heated seat, phone mount and charger, additional brake light, HID projector retrofit, and some other stuff.

I run an Escort radar detector suction cupped to my gas tank, and I've got red LED's mounted below the top of the windscreen that activate on alarm. It works decent, however I can't read the detector so I end up slowing down for false alarms a lot.

I mounted a set of Bose Quiet Comfort 35 headphones in my helmet, and connect those to my phone via Bluetooth.
