I had these on my Yamaha Road Star and it's the reason I bought a set or my 2011 Kawasaki Voyager. The rotating off and on heat switch is not made to fit the extra large sized handle bars. They are at least one and a half inch or more in diameter. I should have looked at the bars before ordering them. The bars are cut down to what looks like one inch where the grips slid on. When the power switch wouldn't fit, I didn't take my grips off, but it looks like the grips will fit. I have used the product before and they work great. There is nothing wrong with the grips, they keep your hands toasty warm. I wish I would have bought them years before.
