Hey Jerry, looking at some of how2's previous posts, it looks like he has the 2015 SESG and that bike did have a hidden antenna.
A comment on the hidden antenna...they MoCo might as well not put out the effort on that. I know some have acceptable reception with theirs from the comments but most, including myself, have no use for them. My '15 SESG had the stock antenna and I thought I'd try the hidden mainly because they had one at the dealer for a huge discount so what the heck. I'm just glad I didn't pay retail or I woulda been very unhappy. I live out in the country and away from the main radio towers so some of the stations on the edge of reception with the normal antenna were non existent with the hidden and some of my stronger stations were full of static with the hidden.
Yes, I tweaked it a few times trying to get the best out of the hidden...no luck. Left it in place and re-attached the regular antenna and never looked back.
