If I had to list the single most important bit of kit to simplify and making motorcycling more enjoyable, I would probably say Quad Lock!
Before I discovered Quad Lock, I had no reliable to way to charge my phone while riding, and no quick, simple and minimal way to attach my phone to my bike.
Quad Lock single handedly changed all that, and transformed riding in the process; it takes two seconds to attach my phone to the Quad Lock mount, and with the press of a button, my phone's charging!
My setup of choice is a Wireless Charger with Vibration Dampener (to protect my phone's internals).
