This is a 2-pin Sumitomo HM 090 connector set (plug, socket, pins, and gasket) that can be used to power your phone charger, heated grips etc. using the accessory plug under the seat or fairing on a Honda CB500X/F/R or NX500 or CB650F. I have a few of them so you can also make a splitter to power multiple things. You will need to crimp the pins on your own but it is easy to do so even without a crimper (just using needle nose pliers for example). $5 for each set.
