Since about 13,00 or 14,000 miles on my 2017 SGS, I have been experiencing some handling oddities. It is similar to what used to be called "bagger wobble," but not as severe. Still, some instability can be felt, especially in higher speed, sweeping turns. There are a handful of factors that could be causing it, but I have eliminated all but one: I have eliminated tire pressure, balance and wear (both are new, full and balanced), I have eliminated the stock suspension, literally, with Legend Suspensions front and rear and I had the neck bearings adjusted and tightened. All that is left is the swingarm and engine mounts. The rear engine mounts are an integral unit with the swingarm and swingarm shaft and has been the source of problems since HD went to rubber mounted motors on the touring bikes many years ago.
I decided that, since the dealer has not been able to replicate the problem (speed limits and such get in the way), I would take my GoPro Sessions and mount one on each side looking right at the pivot shaft. The ends of the shaft are supposed to vibrate a little within the mount, but what I captured on video seems to be excessive. The dealer "isn't so sure," they say they can't be sure if it is a warranty issue without taking it apart - and if they determine it's not, it's out of my pocket. Here are the two videos, right and left. This dropbox link goes to the videos.
