If your 2013 Duke has the same switch housings and handlebar as the 2015 model, (I believe it does), then the G2 will fit. The G2 has the largest cam that will fit within the OEM switch module. I have one and it is a very nice upgrade, with a little shorter travel even than the OEM 2015 throttle, whose travel was lessened compared to the 2013-14 models. The G2 offers a luxuriously smooth operation. A fine piece.
