Heated grips

Not sure what brand I used but they're universal for any bike. They are simply stickers with heater elements built in that stick to the bars and you slide the grips back over. I mounted the switch on a piece of aluminium between the headlight shell and left fork leg. It's neat and tucked away but still acessible. I power them off the aux power outlet under the seat ('06). During the summer I can unplug and connect my tankbag SAE power extension to charge my phone and whatnot. With Acerbis handguards breaking the wind the grip heaters are very effective down to just below freezing.
