For those that have made the change to the Wild One "chubby" bars we no longer have standard 1" handlebars. Except that they are standard size bars from the clamps on out. So wonder if these would still work; or not?
Call Wild One and check. I had the 575s and the inside was the same size as the OEM bars. When I spoke to Wild One, they told me that the bars are made by taking OEM sized tubing, and sliding a larger fatter tube over it making them Chubby, and then bending them all together as one piece.
Personally, I wonder about even heat distribution with those bar end heaters. I used to have the foil wrap heater elements, and found the heat to be uneven. The grip on the clutch side is fixed on the bars, so the heat transfer was pretty direct making them very hot, very fast. The throttle side was a different story. Since the throttle grip spins, and floats off the bar, the heat is not transfered directly. Consequently I found the right grip to be less warm than the left one. I solved this by going with HotGrips.
