Just installed anti gravity on my 1199. Fit was not too bad just removed rubber gasket on the base of battery holder and you might have to pull on wires a bit because they tend to run a bit short. Also the nut which comes with anti gravity to secure the wires to terminal is big so you would have to use the old one and probably have to place a little cardboard or foam piece inside the battery terminal to align it. Bikes starts strong cold or warm. Its been a month so fingers crossed it will hold up for a while.
