The throttle response on my wife's 2016 Icon is a little too, shall we say peppy. Looking around on here it seems that is normal in the early version of that bike due to the throttle tube and that the throttle tubes off a 2017 and the Desert Sled are a little more progressive, softer, and dare I say gentle. She would definitely prefer that. I saw a couple of threads where people are looking for the older tube so here is your chance. I'm in NJ but travel throughout NY and New England often so if you are in the area we can meet up to save on shipping.
