I just ordered a 2017 Icon with heated grips... asked my dealer if the progressive throttle tube reportedly found on the desert sled was on other 2017 models and would it work with heated grips... he didn't know, but he did tell me the heated grips for 2017 have a different part number, so _maybe_ the progressive throttle tube is included in the 2017 OEM heated grips... Ask your dealer to find out for you if this is of interest!
